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。
