Download files from multiple URL s and download it as zip format

Hello friends, here is the code for how to download files from multiple url and download is as zip format in PHP.
If you have any doubt in PHP function's please refer php.net.

Let's start!!!

We can give url's as array format like below

<?php 
$urls = array(
         'http://skidvis.com/WordpressCheatSheet.pdf',         
         'http://andywibbels.com/files/WordPress_Cheatsheet_v1.pdf'          
 ); 
 ?>

Create a random folder using mkdir() to download your file in it.

<?php 
$rand=rand(1,1000000000); 
$mkdir=mkdir($rand); 
?>

Create a zip file to add those file in it.

<?php 
$zip = new ZipArchive; 
$zip-&gt;open('file.zip', ZipArchive::CREATE); 
?>

File mentioned in the URL will be downloaded into our random folder which is created in our server.

<?php 
foreach ($urls as $url){
     $path=pathinfo($url);     
  $path = $rand.'/'.$path['basename'];     
  $zip-&gt;addFile($path);     
  $fileopen = fopen($path, 'w');     
  $init = curl_init($url);     
  curl_setopt($init, CURLOPT_FILE, $fileopen);     
  $data = curl_exec($init);     
  curl_close($init);     
  fclose($fileopen); 
} 
?>

Close the zip.

<?php $zip-&gt;close(); ?>

Check whether the zip file is created or not. If it is created, read that zip file and move it into an temporary variable and then delete the zip file using 'unlink()' function.

<?php 
 if(file_exists("file.zip")){
      $temp = file_get_contents("file.zip");     
   unlink("file.zip"); 
 } 
 delete_directory($rand); 
?>

Here is our zip file download block:) We can enable download by using header function.

<?php 
 header('Content-Type: application/octet-stream'); 
 header('Content-Disposition: attachment; filename=file.zip'); 
 header('Content-Transfer-Encoding: binary'); 
 echo $temp; 
?>

Function to delete our temporary folder.

<?php
function delete_directory($dirname) {
    if (is_dir($dirname))       
    $dir_handle = opendir($dirname);    
 if (!$dir_handle)       
    return false;    
 while($file = readdir($dir_handle)) 
 {
    if ($file != "." &amp;&amp; $file != "..") 
           {
  if (!is_dir($dirname."/".$file))             
  unlink($dirname."/".$file);          
  else             
  delete_directory($dirname.'/'.$file);           
    }    
 }
    closedir($dir_handle);    
    rmdir($dirname);    
    return true; 
} 
?>
