php 创建zip,php简单创建zip压缩文件的方法

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);

}

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');

希望本文所述对大家PHP程序设计有所帮助。
