Thank you for your concise article.

missing semicolon – should read
$page = “default”;

By example, to extract the page topic, book and page and the number with this path: ‘/support/bash/8′ you must pass $default with
array(‘topic’ => ‘defaulttopic’,'book’=>’defaultbook’,'page’=>1)

The following elementh in the path will be returner in a name = value pairs as follows: (/support/bash/8/link/title1)

array(
‘topic’ => ‘support’,
‘book’ => ‘bash’,
‘page’ => 8,
‘link’ => ‘title1′,
)

Enjoy.
