PHP - If URL contains string

Question

I am trying to check with PHP if the user is on some specific pages. Currently I am doing it like this:

<?php if($_SERVER['REQUEST_URI'] == "/forum/"){echo "class='active'";} ?>

Although, this only works if the URL is http://example.com/forum/

How can I make the above code works, on both /forum/ but also on /forum/??

Example:

http://example.com/forum/anotherpage

You can use a startswith function (see this stackoverflow post: startsWith() and endsWith() functions in PHP). Here, you test would be:

if (startsWith ($_SERVER['REQUEST_URI'], '/forum/'))

You can also use a regexp: http://php.net/manual/en/regex.examples.php. Here, your test would be:

if (preg_match ('#^/forum/#', $_SERVER['REQUEST_URI']))

Hope this helps.

That works perfectly! (Used the preg_match solution). Question: What's the #^ before /forum/ representing)

# is the regexp delimiter. It can be anything (often # or /, but you need to escape this delimiter in the regexp, so / isn't really good there). ^ mean begining of the string.

I'd advice against using regex for this especially if you need to check multiple URLs it will be a performance killer compared to other solutions.

@TomToms Would you advise "startsWith"?

If you just need it for one url yes, for multiple I would use an explode().
