[SOLVED] Cant seem to get preg_replace to work!

[emma57573]

What Im trying to do is if somebody types in www.theirdomain

 

It removes the www. part and they are just left with theirdomain

 

 

MY Code

$domain=$_REQUEST["domain"];
$patterns[0] = '/www./';
$replacements[0] = '';
preg_replace($patterns, $replacements, $domain);

 

It outputs www.theirdomain  so does not remove the www. bit as I want it to? Any ideas where I am going wrong?

Ive now tried taking out the slashes and got this error

 

[phpBB Debug] PHP Notice: in file /home/misimeuk/public_html/store_infotest.php on line 31: preg_replace() [function.preg-replace]: Delimiter must not be alphanumeric or backslash

 

Does that mean I cant use preg_replace with a '.'  :-\

Ive fixed this with the following:

$domain=$_REQUEST["domain"];


$patterns = "www.";
$replacements = "";
$domain = str_replace($patterns, $replacements, $domain);

 

Sometimes just writing out te question helps you think with a clear head
