checking dead links

Anon

Hi, I've made an php tool for administrating a lot of different files on different servers, and when the servers are down, nobody can download anything. So, I thought, I could make a 'link checker', so anyone can see is this file 'up' or 'down' before they click on the file.

First I downloaded from www.hotscripts.com a link checker, but this thing is not working.

This is code from this script, I just modified it a litle bit:

$link = "http://www.xxxxxxxx.com/download/xxx.exe";

$check = fsockopen($link, 80, &$errno, &$errstr, 30);

if(!$check)
{
echo "$link DOWN !!\n";
}

else
{
echo "$link OK - $check !!\n";
}

It works if I if $link="http://www.php.net", but it's not working with files.

So I tried something else using some other commands (instead of fsockopen) like:
- filesize — Gets file size (if can't get it, the file is probably down)
- linkinfo — Gets information about a link

...

but these commands work only if files are on my server (where the script is). if the file is somewhere outside, nothing happens, because it can't reach it.

My question is:
Are there any other 'link checkers', or do you have any suggestions how to solve this.

Thanx a lot

if $link="/download/xxxx.exe", everything is ok, but if $link="http://www.xxxxxx.com/download/xxxx.exe" the script is not functioning. I can't use ftp access to these other servers, so I can't use ftp commands.

any suggestions??

but what about

$link = 'www.xxxxxx.com/download/xxxx.exe';

sometimes putting in or taking out the http:// can make a difference, although I admit, putting it IN normally helps!

Also, why not just use /download/xxxx.exe if that way works?

I can use "download/xxxx.exe" if the file is on my local server (where the script is), there are some files on other servers, and I the only way to link to them is over urls "http://www....".
