How to compare url with string variable?

Question

PHP

Hello!
Help solve this issue.
There is a variable to which a part of the url-address is passed. That is, for example, www.site.com/xxxx/. Where xxxx is what is being passed to the variable.
This variable must be compared with the URL of the page the user is on, and depending on this, display a specific message.
At the same time, so that if xxxx/yyyy is passed to the variable, it would display a message specific to yyyy, and not xxxx.

<?$pageurl = $APPLICATION->GetCurPage();?> //получаем урл страницы
<?if (preg_match($pages['PAGE'], $pageurl)):?> // если совпадают, что-то делаем...
....
<?endif;?>

Thanks in advance.

You can get the last "fragment" from the url. For example like this:

$input = 'xxx/yyy/zzz';
$last_part = substr($input, 1 + strrpos($input, '/')); // zzz

And compare with him.
PS: If you're doing this in a template, then something went wrong, IMHO.
