This article mainly introduces php's simple method of creating zip compressed files. The example analyzes php's skills related to file compression based on ZipArchive, for more information about how to create a zip file in php, see the following example. We will share this with you for your reference. The details are as follows:
/* 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; } //vars $valid_files = array(); //if files were passed in... if(is_array($files)) { //cycle through each file foreach($files as $file) { //make sure the file exists if(file_exists($file)) { $valid_files[] = $file; } } } //if we have good files... if(count($valid_files)) { //create the archive $zip = new ZipArchive(); if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { return false; } //add the files foreach($valid_files as $file) { $zip->addFile($file,$file); } //debug //echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status; //close the zip -- done! $zip->close(); //check to make sure the file exists return file_exists($destination); } else { return false; }}
Usage:
$files_to_zip = array( 'preload-images/1.jpg', 'preload-images/2.jpg', 'preload-images/5.jpg', 'kwicks/ringo.gif', 'rod.jpg', 'reddit.gif');//if true, good; if false, zip creation failed$result = create_zip($files_to_zip,'my-archive.zip');
