php方面的问题，关于压缩下载

[pizi611]

什么语句，可以将某个指定文件.html或.php格式的文件压缩成.zip或.rar的压缩包，并生成下载链接供客户下载？
最近在考虑这个问题?

$z = new PHPZip(); //新建立一个zip的类

方法一：
$z -> Zip("", "out1.zip"); //添加当前目录和子目录下的所有档案


方法二：
$files=array('1.txt','gb.txt');
$files[]='5.txt';
$z -> Zip($files, "out2.zip"); //添加文件列表


方法三：
$z -> Zip("/usr/local/sext/", "out3.zip"); //添加指定目录

有没有解有密码的压缩包代码啊，比如密码是1234

[pizi611]

更方便的方法：
<?php
$data = implode("", file("house.txt"));
$gzdata = gzencode($data, 9);
$fp = fopen("house.txt.gz", "w");
fwrite($fp, $gzdata);
fclose($fp);
echo "下载：<a href='house.txt.gz'>house.txt.gz</a>";
?>

给你个地址：http://www.isphp.net/phpZip/
这个也许对你有帮助！

[bear88]

include_once("PHPZip.php");
$z = new PHPZip();
$z -> Zip("", "out1.zip");
我这样压缩当前目录和子目录下的所有文件怎么不行列??

[bear88]

请教大家我用phpzip生成的压缩文件为什么只能压缩11个html文件,多一个解压时就报错呢?
C:\Documents and Settings\Administrator\Local Settings\Temporary Internet Files\Content.IE5\OTO5IV0P\2[1].zip: 压缩文件结尾出现异常

[bear88]

为什么没人帮我看看呢??
