I want to be able to check if a URL is live or not. Basically I want to make a function I can call and supply the URL, and it checks to see if the URL is currently up and running or not. I'm using html, javascript, and php. Currently I'm just doing this with php:

function URLIsLive($URL)
{
return fopen($URL, 'r');
}

It does work for what I need, but it is painfully slow, whether the websites are up or not. It takes about 15 seconds to load the page, which sux. Is there a faster way to do this?

Thanks. Dan

Well, I tried using file_exists($URL); but that just returns false for everything, so I can't use that. And I was looking at the get_headers() function, but it's only available in PHP 5 and I'm still using 4.3.10. Any other suggestions? I might end up upgrading to PHP 5, I just hope I don't run into any problems and that everything will still work correctly.

Personally, I prefer to usr Perl, I only use PHP when my boss insists, PHP is 10yrs behind Perl in its development.

Here's another PHP function that is compatible with PHP4.

Here's another function that would be than the get_meta_tags and is compatible with PHP4.

http://us3.php.net/manual/en/function.header.php

Oops, forget that last one, it's for sending not retrieving the headers.

Well, I tried using the get_meta_tags() function, but that took even longer than the fopen(), and it returned false for some sites that were up and running. Any other ideas? Thanks.

I'm open to trying other things to. If I was to try and do this with Perl, what would I need to do?
