PHP: How to Extract Query String (from a URL) Into an Associative Array in PHP

If you have a query string (such as ?a=foo&b=bar) and want to convert that into a PHP array, this is how to do it.

Let's take a full example, where we begin with a URL, get the query string part of it, then convert that into an array.

  1.         $url = "https://example.com/?foo=bar&foo2=bar2";
  2.         $parsed_url = parse_url($url);
  3.         // $parsed_url is an array of the parts of the URL, such as host, query_string, path, etc
  4.         $query_string = $parsed_url["query"];
  5.         // $query_string is now foo=bar&foo2=bar2
  6.  
  7.         // now let's convert that into an array:
  8.         // don't forget the 2nd param - it is the variable where the array will be
  9.          parse_str($query_string,$array_of_query_string);
  10.  
  11.  
  12.         return $array_of_query_string;

array(2) {
      ["foo"]=> string(3) "bar"
      ["foo2"]=> string(4) "bar2"
      }
