Reading $_GET values from a URL String in PHP was something I had been interested in for a while. It was quite simple to read the $_GET values from the current page’s URL (obviously), but what if you were using AJAX and passing a URL to figure out what data needed to be passed/used? There’s several other reasons why you may need this, but I digress.
While looking for a way to read $_GET variables from a string in PHP, I stumbled across this forum post on Stack Exchange.
parse_str( parse_url( $url, PHP_URL_QUERY ), $array );
