Topic: Detect a word within a string

[d_barszczak]

Hi all,

Once again i have been tripped up by regex so hope you can help.

I have a hitcounter script that submits an id and the url of the page the script was run. I need to be able to detect a domain within the url i.e.

Code: [Select]

// Check to see if site is registered.

$domain = "integrateditsystems.co.uk";
$url = "http://www.integrateditsystems.co.uk/support";

if ($domain exists within $url) return true else false; // Help Me!!

Why do you need regexp for this? Just use http://php.net/strpos

And remember the opposite of "===" is "!==".

Of course, if you just do what you want directly, it would also match "http://www.phishing.com/integrateditsystems.co.uk/trickedyou/".

Hmm good point...

I need to allow for sub domains so i could do something like "http://*.integrateditsystems.co.uk" or require a hitcounter for each sub domain.

Will have to have a think about this then.
