[Dynamic PHP router]

Hi all, I have built a basic router for my slug urls to work. However I'm trying to make it so that if a page is created (maybe for a blog) that the router would automatically work without have to hard code it in.

This is my current code where I've hard coded the link 'post-one' to work:

    
$request = $_SERVER['REQUEST_URI'];
switch ($request) {

case '/blog/post-one':
         $_GET['page_slug'] = 'post-one';
        require __DIR__ . '/views/blog/page.php';
        break;

The below code won't work but hopefully gives an idea what I am trying to acheive where if a new post is created the 'page_slug' is retrieved and the dynamic link is created. Anyone know how something like this could work?

 

$request = $_SERVER['REQUEST_URI'];
switch ($request) {

	case '/blog/'.$_GET['page_slug'].'':
         $_GET['page_slug'] = $rows["page_slug"];
        require __DIR__ . '/views/blog/page.php';
        break;

Any help most appriciated.
