regular expression

I'm trying to only retrieve these urls

also without the www.

i wrote this but it doesn't work

^{[url]http:///urltewlzbox.+[org|com|net]$}

can someone give help me out here im not that good with regex

Hi,

the following regular expression should match these url's
with and without [url]http://[/url]
and
with and without www.

$theString="http://tewlzbox.net";

if (preg_match("/^(http:\\/\\/)?(www\\.)?tewlzbox\\.(org|com|net)$/",$theString)) {
    echo "matched.";
}

sorry something else i wasnt clear about i need to to also recognize the url if it has like index.php or downloads/file.zip or something

a . is any character, * means the number of various chars: 0-xxx

so insert a .* before the $ which symbolizes the end of the string
