Create Zip Archive File using PHP ZipArchive

Do you want to place certain files on a zip archive file? In php this is possible using the ZipArchive class - a file archive, compressed with Zip. Below is the sample code program of this functionality.

<?php

//sample files in an array to be compressed
$files = array(
    'images/img1.png',
    'images/img2.png',
    'images/img3.png',
    'images/img4.png',
    'images/img5.png'
);

//returns true if creation succeed and false if zip creation failed
$result = create_zip($files,'my-archive.zip');

//function that creates a compressed zip file
function create_zip($files = array(),$destination = '',$overwrite = false) {
    //if the zip file already exists and overwrite is false, return false
    if(file_exists($destination) && !$overwrite) { return false; }
    //variable declaration
    $valid_files = array();
    //if files are valid
    if(is_array($files)) {
        //loops and check each file
        foreach($files as $file) {
            //check if file exists and store in array
            if(file_exists($file)) {
                $valid_files[] = $file;
            }
        }
    }
    //check if there are valid files
    if(count($valid_files)) {
       //create the zip archive object
       $zip = new ZipArchive();
       if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE :     ZIPARCHIVE::CREATE) !== true) {
           return false;
       }
        //add files to the object
        foreach($valid_files as $file) {
          $zip->addFile($file,$file);
        }

       //close the zip after adding the files
        $zip->close();

        //check if the destination file exists
        return file_exists($destination);
    }
    else {
        return false;
    }
}

?>
