How to Make Zip File and Archive Folder In PHP?

We will be discussing about creating ZIP archive using PHP script. I  will be mentioning  a PHP script to generate ZIP archive file below. This function zips all the inner files and folders of a folder.

You need to have PHP version >= 5.2.0. If you are using following script in live server then you need to set write permission to zip file.

As a matter of fact,  PHP’s ZIP class provides all the functionalities. To make the process a bit faster for you, I’ve mentioned a create_zip_folder  function for ease.

------- Code Started ----------

function create_zip_folder(){

  // Get real path for folder

  $folder_to_zip = realpath("path-to-folder");

  

  //saving zip  

  $zipname = "zip-file-name.zip";

  // we are using try and catch

// you can run the script without the try..catch

  try{

  // Initialize archive object

  zip = new ZipArchive();

  $zip->open( $zipname, ZipArchive::CREATE | ZipArchive::OVERWRITE);

  // Create recursive directory iterator

  $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($folder_to_zip), RecursiveIteratorIterator::LEAVES_ONLY );

  foreach ($files as $name => $file) {

   // Skip directories (they would be added automatically)

     if (!$file->isDir()) {

         // Get real and relative path for current file

      $filePath = $file->getRealPath();

              $relativePath = substr($filePath, strlen($folder_to_zip) + 1);

        

             // Add current file to archive

             zip->addFile($filePath, $relativePath);

     } // if ends

     } // foreach ends

   echo "zip is generated";

} catch( Exception $e ){

// catch message  for unable to generate zip

}

}// function ends

//call the function

create_zip_folder();

------- End Code  ----------

You can also pass the parameter instead of hardcore path and zip file name. Just need to make a little tweak in the script.

If you want download the archive file

// then send the headers to foce download the zip file

// replace $zipname with your 'zip-filename.zip'

header("Content-type: application/zip");

header("Content-Disposition: attachment; filename=$zipname ");

header("Pragma: no-cache");

header("Expires: 0");

readfile($zipname);

exit;
