How to Create Zip File using PHP Code



In this post I will show you how to create zip file in PHP Programming Language. With the help of this code you can create zip file by using PHP script. I will write short line of php code that converts the selected files formate in zip file formate. This script will helpful to eCommerce website like online sales of Images, PDF File or Document file etc. So, User can select files and download them to zip commpressed formate. I have used php extension like php_zip. First you have to enabled php_zip extension. This extension will load zip library into php code. With the help of this library we can convert selected files into zip file formate.

Source Code



create_zip.php


 <?php  
 $error = ""; //error holder  
 if(isset($_POST['createpdf']))  
 {  
      $post = $_POST;   
      $file_folder = "files/"; // folder to load files  
      if(extension_loaded('zip'))  
      {   
           // Checking ZIP extension is available  
           if(isset($post['files']) and count($post['files']) > 0)  
           {   
                // Checking files are selected  
                $zip = new ZipArchive(); // Load zip library   
                $zip_name = time().".zip";           // Zip name  
                if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)  
                {   
                     // Opening zip file to load files  
                     $error .= "* Sorry ZIP creation failed at this time";  
                }  
                foreach($post['files'] as $file)  
                {   
                     $zip->addFile($file_folder.$file); // Adding files into zip  
                }  
                $zip->close();  
                if(file_exists($zip_name))  
                {  
                     // push to download the zip  
                     header('Content-type: application/zip');  
                     header('Content-Disposition: attachment; filename="'.$zip_name.'"');  
                     readfile($zip_name);  
                     // remove zip file is exists in temp path  
                     unlink($zip_name);  
                }  
           }  
           else  
           {  
                $error .= "* Please select file to zip ";  
           }  
      }  
      else  
      {  
           $error .= "* You dont have ZIP extension";  
      }  
 }
