本文实例讲述了php生成zip文件类。分享给大家供大家参考。具体如下:

<?php
 /*
  by:   matt ford
  purpose: basic class to create zipfiles
 */
class zipfile {
 public $files = array();
 public $settings = null;
 public $fileinfo = array (
   "name" => "",
   "numfiles" => 0,
   "fullfilepath" => ""

$settings = array (

$zipfile = new zipfile($settings);
$zipfile->files = array (
  "./images/navoff.jpg",
  "./images/navon.jpg"
 );
list($success, $error) = $zipfile->create();
if ($success === true) {
 //success
}
else {
 //error because: $error
}
?>

希望本文所述对大家的php程序设计有所帮助。
