Images to Video making php script using FFMPEG

Hi Geeks, This Article is based on Images to Video making php script using FFMPEG , So I am providing you the complete steps to setup the FFMPEG in windows and linux environment. FFMPEG is very good Extension for php where we can process many type of operations on audio and video like Images to video convert ,images and audio to video ,Generate Thumbnail file from video. So I have tried it on my windows system . Steps to install FFMPEG on windows or localhost: Step 1: Download the Static build for windows from following page http://ffmpeg.zeranoe.com/builds/ there will be a button for download as in the screenshot Step 2: Install prerequisite extensions Before making any php script please make available the GD2 Library from your php.ini by just uncommenting following lines(removing semicolons from start of these lines ;extension=php_gd.dll ;extension=php_gd2.dll Step 3: Extract the downloaded zip and Inside Bin folder you will find ffmpeg.exe Copy that file in your project folder in htdocs Eg: slideshow_project Now we have all images which we need to convert into video are in any folder of this projects like Images: there should be pattern of images name like pic1.jpg,pic2.jpg as so on… Step 4: write and execute a command for images to video conversion, following is the command $command1="ffmpeg -f image2 -r 1/1 -i images/pic%d.jpg -vf fps=25 test1.mp4"; //command for every 1 second image change in video exec($command1); above command is useful with creating a slideshow video where 2 second images will change and if you want to increase slide change duration for 3 second then you need to replace 1/1 to 1/3 from above command. Now if you want to mix audio along with images then following command will work $command2="ffmpeg -f image2 -r 1/5 -i images/pic%d.jpg -i audio/my_recording.mp3 -vf fps=25 test2.mp4"; //command for every 5 second image change in video along with my_recording.mp3 playing in background exec($command2); Assuming you have my_recording.mp3 in audio folder of project Installing FFMPEG in linux servers by following command sudo apt-get install ffmpeg In that case you don’t need to follow Step 1 and Step 3 If you are having any problem then please put your comments below , I would love to help you

Pagination code using php and mysql

Hi Geeks, We have gone through some user requests for pagination code for php mysql project.So we have created a simple class where you can easily create pagination for any grid or listing. following are the simple steps for making a pagination system in php. Step 1: Create a class file ‘Paginator.class.php’ in your project with following code snippet _conn = $conn; $this->_query = $query; $rs= $this->_conn->query( $this->_query ); $this->_total = $rs->num_rows; } public function getData( $limit = 10, $page = 1 ) { $this->_limit = $limit; $this->_page = $page; if ( $this->_limit == 'all' ) { $query = $this->_query; } else { $offset=( ( $this->_page - 1 ) * $this->_limit ); $query = $this->_query . " LIMIT " . $offset . ", $this->_limit"; } $rs = $this->_conn->query( $query ); $results=array(); while ( $row = $rs->fetch_assoc() ) { $results[] = $row; } $result = new stdClass(); $result->page = $this->_page; $result->limit = $this->_limit; $result->total = $this->_total; $result->data = $results; return $result; } public function append_existing_query_string($qstring) { if(isset($_GET)) { foreach($_GET as $k=>$v) { $qstring.="&".$k."=".$v; } } return $qstring; } public function createLinks( $links, $list_class ) { if ( $this->_limit == 'all' ) { return ''; } $last = ceil( $this->_total / $this->_limit ); $start = ( ( $this->_page - $links ) > 0 ) ? $this->_page - $links : 1; $end = ( ( $this->_page + $links ) _page + $links : $last; $html = ''; $class = ( $this->_page == 1 ) ? "disabled" : ""; // $qstring='?limit=' . $this->_limit . '&page=' . ( $this->_page - 1 ); $qstring=$this->append_existing_query_string($qstring); // $html .= '«'; if ( $start > 1 ) { // $qstring='?limit=' . $this->_limit . '&page=1'; $qstring=$this->append_existing_query_string($qstring); // $html .= '1'; $html .= '...'; } for ( $i = $start ; $i _page == $i ) ? "active" : ""; // $qstring='?limit=' . $this->_limit . '&page=' . $i; $qstring=$this->append_existing_query_string($qstring); // $html .= '' . $i . ''; } if ( $end ...'; // $qstring='?limit=' . $this->_limit . '&page=' . $last; $qstring=$this->append_existing_query_string($qstring); // $html .= '' . $last . ''; } $class = ( $this->_page == $last ) ? "disabled" : ""; $qstring='?limit=' . $this->_limit . '&page=' . ( $this->_page + 1 ); $qstring=$this->append_existing_query_string($qstring); $html .= '»'; $html .= 'Total records : '.$this->_total.''; return $html; }} ?> Step 2: Include the paging class before extracting data to showStep 3: Now extract the data for any page as following getData( $limit, $page ); ?> Step 4 : Now we are ready with data. So just showing the data and links as followingShow the data first and after it showing the pagination links as following: <th>Customer Id</th> <th>Customer Name</th> <th>Customer Email</th> <th>Customer Address</th> </tr> </thead> <tbody> <?php if(isset($results) && count( $results->data ) > 0){ for( $i = 0; $i < count( $results->data ); $i++ ) { ?> <tr> <td><?php echo $results->data[$i]['id']; ?></td> <td><?php echo $results->data[$i]['name']; ?></td> <td><?php echo $results->data[$i]['email']; ?></td> <td><?php echo $results->data[$i]['address']; ?></td> </tr> <?php } } ?> </tbody> </table>Show the paging links after the datacreateLinks( $links, $class="pagination"); ?>

form validation library in php

Hi Geeks, Today i am sharing a generic class for Form validation library in php & it also populate if form validation failed. First of all you can download the ‘form validation library in php’ by clicking on following url. https://github.com/g10dra/form_validation_php/blob/master/class.validation.php Now in this class you can validate the require,numeric,file-extension,match password & confirm password,validate url and other validation also. It is having a validation with database like is_unique in mysql database where you need pass the db connection if you want to user is_unique validation. Step 1: Include & Initialize the class in header or before your form s following: //include the form validation class// require 'class.validation.php'; or any of your path where you have save the class $db_details=array();//array for db details for validation some fields like is_unique from DB. //pass the varribale dynamic or static $db_details['db_host']=DB_HOST; $db_details['db_user']=DB_USER; $db_details['db_password']=DB_PASS; $db_details['db_name']=DB_NAME; $validation= new validation($db_details); // Step 2: Create a HTML FORM we are assuming that we have a form for add/edit ‘Advertise campaign’ form Read the full comments in code Add / Update Campaign num_rows( $query ) > 0 ) { $_edited_data = $database->get_results( $query ); $_edited_data=$_edited_data[0]; } else{ header("location:campaign.php?err=something bad happen !"); } } else { //add time initialize the blank data in edit data varriable ,if we are add action $_edited_data=array(); $_edited_data['ad_name']=""; $_edited_data['end_url']=""; $_edited_data['campaign_type']=""; $_edited_data['dimension']=""; $_edited_data['is_active']=""; } ?> </div> <div class="panel-body"> <form enctype="multipart/form-data" method="post"> <input type="hidden" name="is_post" value="1" />  <input type="hidden" name="edit_id" value="<?php echo (isset($_GET['id']))? $_GET['id'] : "0"; ?>" />  <fieldset> <div class="form-group"> <label>Ad Campaign Name</label> <input value="<?php echo $validation->set_val("ad_name",$_edited_data['ad_name']); ?>" name="ad_name" class="form-control" placeholder="Ad campaign name" type="text"> <?php echo $validation->error_message("ad_name","<span style='color:red'>");

Step 4: Now need to post the form and recieve data and show errors, Recieve post Before the HTML form if(isset($_POST['is_post'])) //check form is posted { extract($_POST);//extract the form in its filed name vars using php function extract //now create a is_unique rule for ad name for AD/EDIT MOde both if(isset($edit_id) && $edit_id!=0)//it means it is in edit mode { $is_unique_expression="tbl_ads::ad_name::a_id!=".$edit_id;

Now you can call the method after including the above class in any php file as follow: setStreamTimeoutWait(20); $vmail->Debug= TRUE; $vmail->Debugoutput= 'html'; $vmail->setEmailFrom('[email protected]');//email which is used to set from headers,you can add your own/company email over here if ($vmail->check($email)) { echo 'email exist!'; } elseif (verifyEmail::validate($email)) { echo 'email valid, but not exist!'; } else { echo 'email not valid and not exist!'; } ?>Now This is our example file where we have passed the email to be check through url parameter and just got the value using GET/REQUEST using php So create a file index.php with following code CHECK EMAIL IS EXISTS LIVE OR NOT <?php include_once 'class.verifyEmail.php'; // $email = $_REQUEST['email']; //pass an email here to test // $vmail = new verifyEmail(); $vmail->setStreamTimeoutWait(20); $vmail->Debug= TRUE; $vmail->Debugoutput= 'html'; $vmail->setEmailFrom('[email protected]'); if ($vmail->check($email)) { echo '<h1>email <' . $email . '> exist!</h1>'; } elseif (verifyEmail::validate($email)) { echo '<h1>email <' . $email . '> valid, but not exist!</h1>'; } else { echo '<h1>email <' . $email . '> not valid and not exist!</h1>'; } ?> </body>STEP 3. Now check the email using url as following http://localhost/email_verify/[email protected] STEP 3. Now check the email using url as following localhost/email_verify/[email protected] Now you can see the output and able to detect email is valid or now see results output – email verify [viraldownloader id=165 text=’Download Source Code’]

How to work with AngularJS as frontend and PHP MYSQL as backend

Hi Geeks, In this tutorial you will learn that how to work with AngularJs as web frontend or in any hybrid app and get retrieve data from database using php and mysql. We have created restful webservice for return records to angular app. Now steps for making a angularjs app with php and mysql – Step 1) Create a database and table for fetching content from the table Note: If you want to use existing database then select you db else create a new db with ‘news_db’ or whatever you want to take a db name. Now Create a table named ‘news’ for getting data by following sql statement CREATE TABLE IF NOT EXISTS news ( id int(12) NOT NULL AUTO_INCREMENT, title varchar(255) NOT NULL, permalink varchar(255) NOT NULL, details text NOT NULL, thumbnail varchar(255) NOT NULL, category_id int(12) NOT NULL, source_id int(12) NOT NULL, datetime int(12) NOT NULL, day int(2) NOT NULL, month int(2) NOT NULL, year int(4) NOT NULL, hits int(12) NOT NULL, published int(1) NOT NULL, PRIMARY KEY (id) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1; Now Dump some dummy records by following insert statement: -- -- Dumping data for table news INSERT INTO news (id, title, permalink, details, thumbnail, category_id, source_id, datetime, day, month, year, hits, published) VALUES (1, 'MY NEWS TITLE 1', '', 'The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 ', '11621455015936.jpg', 1, 0, 1455015936, 9, 2, 2016, 45, 1), (2, 'MY NEWS TITLE 2', '', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. ', '76911455015952.jpg', 2, 0, 1455015952, 9, 2, 2016, 73, 0); Step 2) Create a file named config.php with following codechange credential according to your database and server host Step 3) Now create a file for webservices named wsdl.php Define Cross origin headers in this file by following codeNow code for getting data from database and provide in restful json format by following code query("SELECT title,details,hits FROM news"); $data=array(); while($rs = $result->fetch_array(MYSQLI_ASSOC)) { $row=array(); $row['title']=addslashes($rs["title"]); $row['details']=addslashes($rs["details"]); $row['hits']=addslashes($rs["hits"]); $data[]=$row; } $jsonData=array(); $jsonData['records']=$data; $conn->close(); echo json_encode($jsonData);} ?>So complete Code for wsdl.php is following query("SELECT title,details,hits FROM news"); $data=array(); while($rs = $result->fetch_array(MYSQLI_ASSOC)) { $row=array(); $row['title']=addslashes($rs["title"]); $row['details']=addslashes($rs["details"]); $row['hits']=addslashes($rs["hits"]); $data[]=$row; } $jsonData=array(); $jsonData['records']=$data; $conn->close(); echo json_encode($jsonData);} ?>Step 4) Now Start with frontend Step for Getting data from database using angularjs as frontend and php & mysql as backed make a file named index.html include the script which i have attached with this postNow make a ng-app with following htmlmake a html table format inside the div for getting data from datasource(php/mysql restful service) as following {{ x.title }} {{ x.details }} {{ x.hits }}Now put the script that call the restful web service and load data to the tablevar app = angular.module('myApp', []); app.controller('newsCtrl', function($scope, $http) { $http.get("http://localhost/angular/wsdl.php?method=load_news") .then(function (response) {$scope.names = response.data.records;}); });Now complete Code for index.html {{ x.title }} {{ x.details }} {{ x.hits }}var app = angular.module('myApp', []); app.controller('newsCtrl', function($scope, $http) { $http.get("http://localhost/angular/wsdl.php?method=load_news") .then(function (response) {$scope.names = response.data.records;}); });Congratulations you have completed with this tutorial please provide comments for this tutorial.

Array to Xml Conversion and Xml to Array Convert in PHP

Hi Geeks, Today i am sharing you a code snippet for converting xml to array with attributes also and vice versa (Convert array to xml). This class is very useful to parse rss feed and to make rss feed in php programming. In this code snippet we have made a class to convert array XML using php code and also retaining its attibues stored into array . It returns the XML in form of DOMDocument class for further manipulation. This class will throw exception if the tag name or attribute name has illegal characters. Usage of this class: //convert array to xml// $php_array = array ();//this is your array data ,it comes from database also or you can define elements in php code also. $root_node="ROOT";//root node of the xml tree like//root , data or anything you want to make super parent tag for the xml $xml = Array2XML::createXML($root_node, $php_array);// echo $xml->saveXML(); //convert xml to array// $xmlstring='';//this varribale will contain xml string $xml_data = Array2XML::XML_TO_ARR($xmlstring);// A. Steps for Convert Array to Xml 1.Create a class named Array2XML with following code in file Array2XML.php formatOutput = $format_output; self::$encoding = $encoding; } /** * Convert an Array to XML * @param string $node_name - name of the root node to be converted * @param array $arr - aray to be converterd * @return DomDocument */ public static function &createXML($node_name, $arr=array()) { $xml = self::getXMLRoot(); $xml->appendChild(self::convert($node_name, $arr)); self::$xml = null; // clear the xml node in the class for 2nd time use. return $xml; } /** * Convert an Array to XML * @param string $node_name - name of the root node to be converted * @param array $arr - aray to be converterd * @return DOMNode */ private static function &convert($node_name, $arr=array()) { //print_arr($node_name); $xml = self::getXMLRoot(); $node = $xml->createElement($node_name); if(is_array($arr)){ // get the attributes first.; if(isset($arr['@attributes'])) { foreach($arr['@attributes'] as $key => $value) { if(!self::isValidTagName($key)) { throw new Exception('[Array2XML] Illegal character in attribute name. attribute: '.$key.' in node: '.$node_name); } $node->setAttribute($key, self::bool2str($value)); } unset($arr['@attributes']); //remove the key from the array once done. } // check if it has a value stored in @value, if yes store the value and return // else check if its directly stored as string if(isset($arr['@value'])) { $node->appendChild($xml->createTextNode(self::bool2str($arr['@value']))); unset($arr['@value']); //remove the key from the array once done. //return from recursion, as a note with value cannot have child nodes. return $node; } else if(isset($arr['@cdata'])) { $node->appendChild($xml->createCDATASection(self::bool2str($arr['@cdata']))); unset($arr['@cdata']); //remove the key from the array once done. //return from recursion, as a note with cdata cannot have child nodes. return $node; } } //create subnodes using recursion if(is_array($arr)){ // recurse to get the node for that key foreach($arr as $key=>$value){ if(!self::isValidTagName($key)) { throw new Exception('[Array2XML] Illegal character in tag name. tag: '.$key.' in node: '.$node_name); } if(is_array($value) && is_numeric(key($value))) { // MORE THAN ONE NODE OF ITS KIND; // if the new array is numeric index, means it is array of nodes of the same kind // it should follow the parent key name foreach($value as $k=>$v){ $node->appendChild(self::convert($key, $v)); } } else { // ONLY ONE NODE OF ITS KIND $node->appendChild(self::convert($key, $value)); } unset($arr[$key]); //remove the key from the array once done. } } // after we are done with all the keys in the array (if it is one) // we check if it has any text value, if yes, append it. if(!is_array($arr)) { $node->appendChild($xml->createTextNode(self::bool2str($arr))); } return $node; } /* * Get the root XML node, if there isn't one, create it. */ private static function getXMLRoot(){ if(empty(self::$xml)) { self::init(); } return self::$xml; } /* * Get string representation of boolean value */ private static function bool2str($v){ //convert boolean to text value. $v = $v === true ?

Steps to create dynamic multilevel menu using php and mysql

Hi Geeks, Today i am sharing you ” Steps to create dynamic multilevel menu using php and mysql” which can be called “example of recusion in php & mysql”. What Exactly recursion is ? Recursion is a technique or Algorithm by which we can go and return the collection of sequenced data with n depth. It is a condition based child search and return the output to the previous stepped varriable’s scope. we can solve many of the programming problems using recursion. In following Example we will sort out a problem where we need to show nested n number of depth relation saved in mysql menu table with having proper opening and closng the and tags in html. Following are the steps : Step 1. Create a mysql Table in your database by executing following sql statement -- -- Table structure for table menu CREATE TABLE IF NOT EXISTS menu ( menu_id int(11) NOT NULL AUTO_INCREMENT, menu_name varchar(255) NOT NULL, parent_id int(11) NOT NULL DEFAULT '0' COMMENT '0 if menu is root level or menuid if this is child on any menu', link varchar(255) NOT NULL, status enum('0','1') NOT NULL DEFAULT '1' COMMENT '0 for disabled menu or 1 for enabled menu', PRIMARY KEY (menu_id) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=37 ; -- -- Dumping data for table menu INSERT INTO menu (menu_id, menu_name, parent_id, link, status) VALUES (1, 'Home', 0, '#home', '1'), (2, 'Web development', 0, '#web-dev', '1'), (3, 'WordPress Development', 0, '#wp-dev', '1'), (4, 'About w3school.info', 0, '#w3school-info', '1'), (5, 'AWS ADMIN', 2, '#', '1'), (6, 'PHP', 2, '#', '1'), (7, 'Javascript', 2, '#', '1'), (8, 'Elastic Ip', 5, '#electic-ip', '1'), (9, 'Load balacing', 5, '#load-balancing', '1'), (10, 'Cluster Indexes', 5, '#cluster-indexes', '1'), (11, 'Rds Db setup', 5, '#rds-db', '1'), (12, 'Framework Development', 6, '#', '1'), (13, 'Ecommerce Development', 6, '#', '1'), (14, 'Cms Development', 6, '#', '1'), (21, 'News & Media', 6, '#', '1'), (22, 'Codeigniter', 12, '#codeigniter', '1'), (23, 'Cake', 12, '#cake-dev', '1'), (24, 'Opencart', 13, '#opencart', '1'), (25, 'Magento', 13, '#magento', '1'), (26, 'Wordpress', 14, '#wordpress-dev', '1'), (27, 'Joomla', 14, '#joomla-dev', '1'), (28, 'Drupal', 14, '#drupal-dev', '1'), (29, 'Ajax', 7, '#ajax-dev', '1'), (30, 'Jquery', 7, '#jquery-dev', '1'), (31, 'Themes', 3, '#theme-dev', '1'), (32, 'Plugins', 3, '#plugin-dev', '1'), (33, 'Custom Post Types', 3, '#', '1'), (34, 'Options', 3, '#wp-options', '1'), (35, 'Testimonials', 33, '#testimonial-dev', '1'), (36, 'Portfolios', 33, '#portfolio-dev', '1'); Step 2.

Implement caching in php website

Hi Experts, Today i am sharing you Step by Step instructions for Implement caching in php website. First of all we have to understand that what is cache exactly and how cache exactly works . What is cache ? Cache is a technique to optimize web page speed,load time and execution . it just reduces database calls and load by delivering contend by cached pages or objects which we saved in file-system or objects .We can Achieve cache with multiple logic like File Storage Cache(Most popular & this article is about itself),Object Stored cache( like Memcache),Application level cache (like Varnish Cache) ,SQL Query Cache. Simply Cache is not a logic or program it is just a concept and that can be achieve with multiple logic or programs/techniques as above. Now See that How Cache works with Server and Client See in Following Figure.Now Step by Step Implement caching in php website Step 1 : Create a Cache class with file name cache.class.php in your website root directory cache_ext=$cache_ext; $this->cache_time=$cache_time; $this->cache_folder=$cache_folder; $this->ignore_pages=$ignore_pages; $this->dynamic_url = "http://".$_SERVER['HTTP_HOST']. $_SERVER['REQUEST_URI'] . $_SERVER['QUERY_STRING']; $this->_cache_file = $this->cache_folder. md5($this->dynamic_url).$this->cache_ext; $this->_ignore_status = (in_array($this->dynamic_url,$this->ignore_pages))?true:false; if($cache_enable==1) { if (!$this->_ignore_status && file_exists($this->_cache_file) && time() - $this->cache_time _cache_file)) { //check Cache exist and it's not expired. ob_start('ob_gzhandler'); //Turn on output buffering, "ob_gzhandler" for the compressed page with gzip. readfile($this->_cache_file); //read Cache file echo '_cache_file)).', Page : '.$this->dynamic_url.' -->'; ob_end_flush(); //Flush and turn off output buffering exit(); //no need to proceed further, exit the flow. } } //Turn on output buffering with gzip compression. ob_start('ob_gzhandler'); }}?>Step 2 : Put Following code Before your website header file/template file or any file where you want to achieve cache. Note : this code should be always upper from your tag starts.Step 3 : In the Footer template or page just After the close tag. cache_folder)) { //create a new folder if we need to mkdir($cache_obj->cache_folder); } if(!$cache_obj->_ignore_status){ $fp = fopen($cache_obj->_cache_file, 'w'); //open file for writing fwrite($fp, ob_get_contents()); //write contents of the output buffer in Cache file fclose($fp); //Close file pointer } ob_end_flush(); //Flush and turn off output buffering?>Step 4 : Check you page and see that for the time you set in code or by default 1 hour you webpage will give same output for all users very quickly. Question : how to verify that cache is implemented or not Answer : load your webpage where you implement this cache system after it CTRL+U or see page source. in that in last of your code there will be a html comment having following text ” cached page by cache class by w3school ” Now Enjoy the Script by https://www.w3school.info/

How to remove index.php from Codeigniter url

Here we will learn how to remove index.php from codeigniter url. Each of codeigniter constructed url contains the value index.php and excluding root url. No url cannot be run without index.php Assume a scenario , we have a website named www.myciportal.com Where we didn’t remove the index.php from url and i have a category with following details category name: techbuzz So by default it’s url will create like following default url : www.myciportal.com/index.php/techbuzz it will not run like this way www.myciportal.com/techbuzz For make this possible we have to work on config and htaccess both and steps are following to achieve this task If you are using mod_rewrite to remove the index.php in each url construct of codeigniter then you have to follow these steps: Step 1: In CI Project root Folder of your project create a .HTACCESS file and place following code in it RewriteEngine on RewriteBase /myprojectname RewriteRule ^(application|system|.svn) index.php/$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [QSA,L] Comments :: In above code myprojectname is passed with RewriteBase , which is the demo project name of our ci project,if you are running on main domain then Redirect base will be / only , or if you are running your project in any directory then you have to specify that name. Now Step 2: in your project >> application/config/config.php Replace following line $config['index_page'] = 'index.php'; with $config['index_page'] = ''; //removed the index.php after htaccess done Now you can run your Codeigniter project and you can see the index.php has been removed from every Controller Action
