I have this url:

example.com/?do=search&q=testing+this+out

I need to store the part after &q= in a variable.

What PHP function would be the best for doing that, explode, slice?

P.S. I use $request_url = $_SERVER['REQUEST_URI']; to get the URI.

• php
• url

If you just need the value of q, you can simply write:

$value = $_GET['q'];

There's parse_url() to slice 'n dice a url into its components, then parse_str() will take a query string and decompose it into a regular key-value array.

$url = 'your url here';
$parts = parse_url($url);
$query = parse_str($parts['query']);
echo $query['q'];

I don't understand why $_GET is not sufficient. But incase it isn't, here:

$ php -r '$url = "http://example.com/?do=search&q=testing+this+out"; $parts = parse_url($url); $vars = explode("&", $parts["query"]); print_r($vars);'
Array
(
    [0] => do=search
    [1] => q=testing+this+out
)

mabye more quick and more simple...

$requested_query_vars = $_SERVER["QUERY_STRING"];

or parse_url() php function

$requested_query_vars = parse_url($request_url, PHP_URL_QUERY);
