本文实例讲述了php简单创建zip压缩文件的方法。分享给大家供大家参考,具体如下:
- /* 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);
- }//phpfensi.com
- else
- {
- return false;
- }
- }
使用方法:
- $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');
