Question

I found this code on the internetz, it checks the current page url;

function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}

So now I can do something like this;

elseif (curPageURL() == "http://www.example.com/pageexample") {
<meta tags here>
}

Great. But I would also like to use this for pagination pages. Those URLs look like this:

http://www.example.com/pageexample?start=30&groep=0
http://www.example.com/pageexample?start=60&groep=0
http://www.example.com/pageexample?start=90&groep=0
[....]
http://www.example.com/pageexample?start=270&groep=0

I could use a if statement for every of those links.. but I would much rather like to use one. Is it possible to add a wildcard or something? Like this I guess (notice the *)

elseif (curPageURL() == "http://www.example.com/pageexample" OR curPageURL() == "http://www.example.com/pageexample?start=*&groep=0") {

edit: I would like to do this for all those URLs because I want to give them the same meta description, <title> and <link rel="canonical". I could do this manually by doing an if-statement for every page (10+ atm) but I figured there was a better way.

Sounds a lot like regex problem:

if (preg_match("#^http://www.example.com/pageexample(\?start=[^&]*&groep=0)?#", curPageURL())) {
    // it matches
}

The expression [^&]* acts like your *.; to match non-empty items, use[^&]+`. It matches these:

http://www.example.com/pageexample
http://www.example.com/pageexample?start=30&groep=0

Update

It’s not entirely clear why you need to compare against the full canonical URL, unless you have multiple domains point to the same code base.
