regex on urls

[stunnaman]

Hey, I'm trying to switch off my mod_rewrite dependency because it's so ridiculous to set up properly and changes server to server.

Anyway, I'm wondering if someone can help me develop a regex/string manip that will take the contents of $_SERVER["REQUEST_URI"] (the path after the tld including the first /) and be able to separate it into variables representing the subfolder structure.

e.g. www.example.com/first/second/third

put first in $1, second in $2, third in $3 etc (ideally extendable to an unlimited number of subfolders)

Thanks for any help!
🙂

You could put it into an array, which might be easier to use anyway rather than an unknown number of $n variables:

$urlVars = explode('/', $url);
array_shift($urlVars); // shift the first element (the domain) out of the array

Let's assume for a second that $_SERVER["REQUEST_URI"] = something like:
www.example.com/first/second/third/four/fifth/sixth.php

$str = 'www.example.com/first/second/third/four/fifth/sixth.php';
preg_match_all('#([^/]+/?)+?#', $str, $matches);
foreach($matches[0] as $val){
   echo $val . '<br />';
}

output:
www.example.com/
first/
second/
third/
four/
fifth/
sixth.php

Is this the result you are looking for?

If you're looking to do Pretty URLs with MVC, here's a nice routing function that I wrote:

function get_route()
{	
	$uri = $_SERVER['REQUEST_URI'];
	$uri_params = array_values(array_filter(explode('/', $uri)));

$size = sizeof($uri_params);
$route_frontend = array
				(
					'site' => 'index', 
					'controller' => 'index', 
					'view' => 'index'
				);

$route_params = array();
for ($i = 0; $i<$size; $i++)
{
	switch($i)
	{
		case 0 :
			$route_frontend['site'] = $uri_params[0];
		break;
		case 1 :
			$route_frontend['controller'] = $uri_params[1];
		break;
		case 2 :
			$route_frontend['view'] = $uri_params[2];
		break;
	}
	if ($i > 2)
	{
		$route_params[$uri_params[$i]] = $uri_params[++$i]; //ninja code by TG
	}
}
$route = array('frontend' => $route_frontend, 'params' => $route_params);
return $route;
}
