Use PHP to remotely download files to space_PHP tutorial

I just moved my blog and planned to migrate the data between the two spaces, but I encountered some problems. The packaged files were too big. I couldn’t help it, so I thought of using PHP to download files remotely
Then I wrote a script!

01	<?php
02	if ($_GET[xfer]) {

03	if ($_POST[from] == "") {
04	print "You forgot to enter a url.";

05	} else {
06	copy("$_POST[from]", "$_POST[to]");

07	$size = round((filesize($_POST[to])/1000000), 3);
08	print "transfer complete.<br>

09	<a><a href="$_POST[from]">$_POST[from]</a><br>
10	<a><a href="$_POST[to]">$_POST[to]</a> : $size MB";

11	}
12	} else {

13	print "<form action="$PHP_SELF?xfer=true" method=post>
14	远程文件下载地址(请带上http://): <input name=from><br>

15	保存文件名: <input name=to><br>
16	<input type=submit value="transload">";

17	}
18	?>

However, not all virtual hosts support it. It depends on whether certain functions are enabled. I don’t know what functions
