[SOLVED] Breaking down a string.

[Lamez]

How do I break down a string?

 

I have a External Link Checker(http://links.krazypicks.com), which will check to see if the URL is in the blacklist that is in the database, but if it is not then it will show a continue warning. Well I want to know how to break down the URL. say they type this in:

 

 

I want to break it down to www.youtube.com, to check, then display the real URL.

 

Does this make sense?  You can just give me a function.

 

-Thanks

Regular Expression is what you are looking for.

What I found with google.

however, I did use "the google", but that does not help at all. is there a function.

parse_url().

 

Read up about it in the PHP manual.

ok so I have this bit:

 

<?php
$link = print_r(parse_url($url));
?>

 

but it is echoing out, and I know it is in an array, but how to I take it out?

 

here is an example of the out put:

 

Array ( [scheme] => http [host] => www.youtube.com [path] => /watch [query] => v=Cqsrq34qDyk )

 

how can I just echo out the host?

[DarkWater]

<?php
$link = parse_url($url);
$host = $link['host'];
?>

Damn we all learn something new everyday... Guess some people just don't know it.

 

Also reading up on it you could also just do:

<?php
$host = parse_url($url, PHP_URL_HOST);
?>
