Example page for "Url Routing with PHP - Part One"
This page contains a simple demonstation for the "Url Routing with PHP - Part One" article. It shows a live example of how the code talked about in the article works. A download of sample code that you can use to experiment is included at the end of this page.

The incoming URL is parsed to obtain the command array.

$_SERVER["REQUEST_URI"] contains '/urlrouter/part_1/commandOne'
Which when exploded creates the following array:
Array ( [0] => [1] => urlrouter [2] => part_1 [3] => commandOne )

$_SERVER["SCRIPT_NAME"] contains '/urlrouter/part_1/index.php'
Which when exploded creates the following array:
Array ( [0] => [1] => urlrouter [2] => part_1 [3] => index.php )

After removing each position in $_SERVER["REQUEST_URI"] that matches the same position in $_SERVER["SCRIPT_NAME"] the following command array is obtained.
Array ( [0] => commandOne )

The command array is then used in a switch statement to select the code to exectute based on the contents of first position of the command array.
