Question

This is a two part question. First how can I grab the last url value from a link when I dont know how deep the value is, for example how can I grab
the last value of sub_4 from the link example below using PHP? And second how can I grab the url value cat=3 and the last url value sub_4 using PHP?

I’m kind of new to PHP so a detailed step by step example would help me out a lot if its not too much trouble.

Thanks in advance!

Here is an example of a URL value.

http://www.example.com/categories/index.php?cat=3&sub_1=sub1&sub_2=sub2&sub_3=sub3&sub_4=sub4

Answer 1

All variables from the hook will be returned on $_GET. So if you want to get that value from the URL, just use:

$_GET['sub_4']

If you want to get a list of all of the possible values:

array_keys($_GET)

This will give you all of the variables.

UPDATE: I just reread your question. I think I better understand what you are looking for. Correct me if I am wrong, but you are not certain how to get the last element of the string? Is that right? So you could potentially have sub_5, sub_6, sub_7 etc. Here is how to get the last element from the string:

end($_GET);
$key = key($_GET);
$last_item = $_GET[$key];

$last_item will now have sub_4 (or what ever the last item is).
