Create Download and Open Zip File in PHP

Introduction

This article describes a simple PHP function that can be used to create a Zip file archive with PHP. The function receives two parameters: an array with the path-name of the files to be added to the archive, and a string with the path-name of the Zip file that will be created. PHP's ZIP class provides all the functionality you need! To make the process a bit easier for you, I've coded a simple create_zip function for you to use in your projects.

• Important: If you work on a Linux system, PHP must have CHMOD write permisions in the directory in which the Zip file archive will be created.

Example

Code to create a Zip file

Let's see one example that shows you how to create a Zip file. Here, I have create a function that creates a Zip file.

<?php

function createZip($files, $zip_file) {

$zip = new ZipArchive;

if($zip->open($zip_file, ZipArchive::CREATE) === TRUE)

{

foreach($files as $file)

{

$zip->addFile($file);

}

$zip->close();

return true;

}

else return false;

}

$files = array('file1.txt', 'image.jpg', 'audio.mp3');

$zip_file = 'final.zip';
