Hi,
How would I remove any text after the forward slash in a string..
Lets say I have
$strdata = "google.com/adsense";
How would I remove the "/" and "adsense".
But I want to make sure I can remove absolutley anything after the forward slash (not just adsense)
How would I go about this?

Im not sure, but you could use $_SERVER['HTTP_HOST']; to get "
www.google.com" straight away.

It will only work to get the domain of the page your on though. Im guessing you'll have to use regex to strip down any other domains.

If you're not comfortable with regex you could use
parse_url()
There
are plenty of pre-written URL/URI regex patterns available through search if you want to go that route.

Could anyone help me out with either regex or parse_url I've been looking around and I just can't figure out how to use the functions properly.
An example piece of code would be great.

There's an example on the documentation page linked.

There may be but as I said, I cant understand it.
I tried the code in the first reply to the function:
Code: Select all
<?php
$url = 'http://username:password@hostname/path?arg=value#anchor';
print_r(parse_url($url));
echo parse_url($url, PHP_URL_PATH);
?>
and all I get is:
Array ( [scheme] => http [host] => hostname [user] => username [pass] => password [path] => /path [query] => arg=value [fragment] => anchor )
Warning: parse_url() expects exactly 1 parameter, 2 given in /******/test.php on line 6

You aren't using PHP 5.1.2 or after, so the second parameter doesn't exist.
ChangeLog
Version Description
5.1.2 Added the component parameter

Use the normal output. Get the element(s) you wish from there.
