Checking a url exists

[mindwarp]

Hi,

I've looked on this newsgroup on google and on php.net, but I can find
a work function which will allow me to check if a url exists?

Can anyone provide me with one?
or point we towards one?

Best regards,

Jules.

I dont have code for this but you can do it fairly easily with sockets.
(see php docs)

1) create a socket resource
2) connect to the socket on port 80
3) send the URL
4) read the response.

Check for errors on each of the steps above

Hi,

I've had a few attempts and always come up with a 200 return code.
I guess 404 handling pages are causing this.

For example...

<?php

$url = 'http://www.whatever.com/ccc';

$fp = @fopen($url, 'r');

if ($fp) {

$headers = stream_get_meta_data($fp);

print_r($headers);

}

$skunk="http://www.emailuser.co.uk";
if (fopen($skunk,'r')===FALSE) {exit;}

Although it doesnt work if the website uses a custom 404 webpage and i
never got around to doing any more work on it .
