phpwind8.7整站压缩

phpwind8.7整站太大了，超过5G，导致pclzip类无法压缩成一个文件，尝试很多办法，create文件列表方式也不行，文件太多,32位操作系统的失败，（我在64位上是测试成功的）。
最后用一个笨办法，分别压缩附件文件夹，就是那个for循环。
<?php
include "pclzip.lib.php";
set_time_limit(0);
$path =  dirname(__FILE__);


function zipdirs($dir,$zipfile){
echo "<br><b>开始压缩...</b><br>";
$archive = new PclZip($zipfile);
$v_list = $archive->create($dir);
if ($v_list == 0) {
die("Error : ".$archive->errorInfo(true));
}
else
echo '压缩成功!'.$zipfile.'<br>';
flush();

}
//zipdirs();


//exit();
