[SOLVED] URLS - Remove and check parts

[supanoob]

I have a system where people can add their favourite sites to my database and people can rate them and comment on them.

 

However i want to check the URL on submittion and if it has http:// at the beginning i want it to remove it. I would also like remove anything after the .com or .co.uk or whatever at the end of the URL so it is taking you directly the to homepage instead of allowing links to images etc.

 

How would i do this?

There is a nice function to parse the components of an URL: http://www.php.net/manual/en/function.parse-url.php

 

You need to extract the host component: parse_url($url,PHP_URL_HOST)

 

So that

 

echo parse_url ('http://www.php.net/manual/en/function.parse-url.php',PHP_URL_HOST);

 

will output "www.php.net"
