Get URL query string parameters

Question

What is the \"less code needed\" way to get parameters from a URL query string which is formatted like the following?

www.mysite.com/category/subcateg

Answer 1

The function parse_str() automatically reads all query parameters into an array.

For example, if the URL is http://www.example.com/page.php?x=100&y=200, the code

$queries = array();
parse_str($_SERVER['QUERY_STRING'], $queries);

will store parameters into the $queries array ($queries['x']=100, $queries['y']=200).

Look at documentation of parse_str

EDIT

According to the PHP documentation, parse_str() should only be used with a second parameter. Using parse_str($_SERVER['QUERY_STRING']) on this URL will create variables $x and $y, which makes the code vulnerable to attacks such as http://www.example.com/page.php?authenticated=1.
