Parse url - asking for advice

whisher06

Hi folks.
I've managed this code:

<?php 
function url(){
	$url= array();
	$requestUri= $_SERVER['REQUEST_URI'];
	$pathParts= pathinfo($requestUri);
	$url['web_root']= $pathParts['dirname'];
	if(strpos($requestUri, '?')===false){
		return $url;
	}
	$queryString= explode('?',$pathParts['basename']);
	if(strpos($queryString[1], '&')===false){
		$frag=sanitize($queryString[1]);
		$url[$frag[0]]= $frag[1];
		return $url;
	}
	$frag= explode('&',$queryString[1]);
	foreach($frag as $propValue){
		$frag= sanitize($propValue);
		$url[$frag[0]]= $frag[1];
	}
	return $url;
}
function sanitize($queryString){
	$frag= explode('=',$queryString);
 	$frag[1]= filter_input(INPUT_GET,$frag[0],FILTER_SANITIZE_STRING);
	return $frag;
}
/*
From konstrukt framework
*/
function normalizePath($path){
	$path = trim($path, "/");
    $parts = Array();
    foreach (explode("/", $path) as $part) {
      $part = urldecode($part);
      if ($part == '..') {
      	if (count($parts) == 0) {
          throw new Exception("Illegal path. Relative level extends below root.");
        }
        array_pop($parts);
      } else {
        $parts[] = urlencode($part);
      }
    }
	return implode('/',$parts);
}
$url= url();
/*
For js, css etc ........
*/
var_dump($url['web_root']);
echo "<br>";
var_dump(normalizePath(implode('/',$url)));
?>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<a href="?page=home">home</a><br />
<a href="?page=home&actions=..">home</a><br />
<a href="?page=home&actions=De andea">home</a><br />
<a href="?page=home&actions=insert&id=12">home</a><br />
</body>
</html>

I'd like to use a think like this in a request class
so I'm asking for advice.

Any comments on how I should be doing this better would be gratefully appreciated 😃

EDIT

I noticed right now that with rewrite rules
doesn't work 🙁

function url(){
	$url= array();
	$url['web_root']= dirname($_SERVER['PHP_SELF']);
	$queryString= $_SERVER['QUERY_STRING'];
	if(empty($queryString)){
		return $url;
	}
	if(strpos($queryString, '&')===false){
		$frag=sanitize($queryString);
		$url[$frag[0]]= $frag[1];
		return $url;
	}
	$frag= explode('&',$queryString);
	foreach($frag as $propValue){
		$frag= sanitize($propValue);
		$url[$frag[0]]= $frag[1];
	}
	return $url;
}

Just a little better :o

coincidentally I was just about ot post this function I developed for the php community - this is a different approach but handles urls pretty well - let me know if there are any bugs this is v1.01
