HomeBackend DevelopmentPHP Tutorialphp打包压缩文件之ZipArchive方法用法分析_PHP

本文实例讲述了php打包压缩文件之ZipArchive方法用法。分享给大家供大家参考,具体如下:

前面说到了php打包压缩文件之PclZip方法,今天来说下另一种更为简单的方法,使用ZipArchive来压缩文件。这个是php的扩展类,自php5.2版本以后就已经支持这个扩展,如果你在使用的时候出现错误,查看下php.ini里面的extension=php_zip.dll前面的分号有没有去掉,然后再重启Apache这样才能使用这个类库。

使用ZipArchive压缩文件是非常简单的,php官网已经给我提供了很多相关示例,大家可以看下 http://www.php.net/manual/zh/class.ziparchive.php,例如:

<&#63;php
$zip = new ZipArchive; //首先实例化这个类
if ($zip->open('test.zip') === TRUE) { //然后查看是否存在test.zip这个压缩包
  $zip->addFile('too.php');
  $zip->addFile('test.php'); //将too.php和test.php两个文件添加到test.zip压缩包中
  $zip->close(); //关闭
  echo 'ok';
} else {
  echo 'failed';
}
&#63;>

下面是一些参数说明:

<&#63;php
/******** ziparchive 可选参数 *******/
/*
1.ZipArchive::addEmptyDir
添加一个新的文件目录
2.ZipArchive::addFile 
将文件添加到指定zip压缩包中。
3.ZipArchive::addFromString 
添加的文件同时将内容添加进去
4.ZipArchive::close 
关闭ziparchive
5.ZipArchive::extractTo 
将压缩包解压
6.ZipArchive::open
打开一个zip压缩包
7.ZipArchive::getStatusString
返回压缩时的状态内容,包括错误信息,压缩信息等等
8.ZipArchive::deleteIndex
删除压缩包中的某一个文件,如:deleteIndex(0)删除第一个文件
9.ZipArchive::deleteName
删除压缩包中的某一个文件名称,同时也将文件删除。
......
*/
&#63;>

总之只要你的php5.2版本以上,使用ZipArchive来进行文件压缩还是比较方便的。具体的和PclZip哪一个运行速度比较快,这个磊子还没有做过测试,大家感兴趣的可以折腾折腾。
