由于所买的虚拟主机没有申请SSH或根本不提供SSH访问，无法直接在shell里用get命令获取远程数据，在转移数据时只能通过FTP下载到本地再上传到另一台主机上，速度很慢，如果能直传就好了
解决方法如下，写个PHP文件在A主机上，直接通过PHP脚本下载B主机上的文件到A主机，代码如下：
<form method=”post”>
文件地址:<input name=”url” size=”50″ /><br>
操作密码:<input name=”pwd” size=”30″ />
<input name=”submit” type=”submit” />
</form>
<?php
$pwd=’abcd’;
if ($_POST['pwd']!=$pwd)
exit(‘Sorry ,you are not validate user!’);
// maximum execution time in seconds
set_time_limit (24 * 60 * 60);
if (!isset($_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);
echo ‘OK,File has been downloaded!’;
}
?>
基中$pwd是操作密码，这样不会被人乱下东西挤爆硬盘了
