Hey All,
I am just begining to learn regex functions in PHP. Anyhow I am trying
to code a preg_replace function which basically cleans a URL.
What I mean is say a url is index.php?page=hello&list=10&start=4 you
pass that URL and say 'list' to the function (shown below) Anyhow I
want that to then return index.php?page=hello&start=4 (see how the
entire list reference is now gone)
Here is what I have come up with so far, though I am yet to test it as
I am coding this at work :)
function stripUrl($url, $url_strip)
{
// Check that $url_strip is in the URL
if(strpos($url,'?') && strpos($url, $url_strip.'='))
{
// Lets clean up the url
$url = preg_replace("/\?|&$url_strip=/", "", $url);
}
return $url;
}
My problem is that, how do I make the preg_replace stop when it
encounters a & in the URL? If anyone could shed some light on this it
would be appreciated,
- Regards, Scott
