大家有没有php下载zip文件的代码_美国VPS

网站要转移打包好了，由于是虚拟空间不支持wget命令，想弄个php代码下载远程空间zip文件，下面代码有问题，不过类似这样的，以前有个这样的php下载文件，可惜不知道在哪里去了

<form method="post">
<input name="url" size="50" />
<input name="submit" type="submit" />
</form>
<?php
// maximum execution time in seconds
set_time_limit (24 * 60 * 60);
if (!isset($_POST[‘submit’])) die();
// folder to save downloaded files to. must end with slash
$destination_folder = ‘temp/’;
$url = $_POST[‘url’];
$newfname = $destination_folder . basename($url);
$file = fopen ($url, "rb");
if ($file) {
$newf = fopen ($newfname, "wb");
if ($newf)
while(!feof($file)) {
fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
}
?>

河北网友:这种主机，在这个年代是没有人用的，打包下载都不支持，正常解压，打包都是基本的功能
香港网友:用的是阿里云的虚拟空间，想把这个香港空间打包下载到阿里云的空间
青海网友:
你用FTP一个一个的下载文件吧，今晚肯定能完成，数据库做好备份也下载
湖北网友:阿里云虚拟机支持的

福建网友:不是解压缩啊！是把其他空间的文件下载到阿里云虚拟空间里面啊！不想上传啊！2个多g文件这得下载和上传到什么时候去，以前有这个php文件，好久没用虚拟空间不知道弄在哪里去了
广西网友:代码网上一抓一大把，自己随便改改就能用。
不过2个g还是别指望php了，下一会就超时了，还是ftp慢慢传吧
云南网友:在目标空间做个上传接收，然后在zip机器用命令行curl 直接POST @file上传？
台湾网友:只能用国内vps下载本地再上传了。

谷歌搜索找了个自己改下代码，大家需要就拿去吧
