PHP Redirection, Youtube fault.

[smithmr8]

Hi,

Have a project, http://ziz.im

URL Shortener.

 

For some reason, shortened youtube links don't work. When used, they go to the youtube page, displaying a message saying the video is not available. But it's the same link (once redirected) as the original link.

 

Any idea what could be causing this ?

Apologies. I was formatting the URL to lower case, which conflicted with the variance in youtube identifiers. Pfft.

 

Is there any good scripts for verifying a URL is valid ? Checks if has http, www, ect..

if you want to check if the url is valid then do something like this:

 

<?php
$url = $_SERVER['HTTP_HOST']; //get domain name of the url submitted

if (stristr($url, "http://"))
{
    //now do the same for www or co.uk, .com etc......
}
else
{
die("url is not valid");
}
?>

Additionally you can use parse_url. Read that manual entry carefully, as it states it does not validate the URL, it merely breaks it down into the components.
