Question

I need a regex string to extract parameters from different types of url, for example using $_SERVER["REQUEST_URI"]:

string 1: “/news/page/4” or string 2: “/news/weekly/page/4”

I need to extract the string without last /page/[ID], I mean only /news/page or /news/weekly/, etc.
How can I do it with preg_replace?

Thank you.

Answer 1

regexp solution:

echo preg_replace('/^([\w\W]*)\/page\/\d*/','$1','/news/weekly/page/4');

outputs:

/news/weekly

but you should use explode solution:

$parts = explode('/', $_SERVER["REQUEST_URI"]);
$url = $parts[0].'/'.$parts[1];
