ACL???? is this right?

[php_hazard_01]

i made an object as an ACL and i was thinking if i made it right?
could someone tell me the flaws of my code and the advantages...and how can i improve it?

thanks, here is the code:
class ACL {

var $_acl_group = array();

var $_acl_ranks = array();

var $_acl_count = 0;

var $_acl_info = null;

var $_acl_return = null;

var $_acl_resource = array();

var $acl_role = array();

var $acl_permissions = array();

function ACL(){

}


function add($resource,$rankName,$permission = "ALLOW"){

if(array_key_exists($rankName,$this->_acl_ranks)){

//if the key has been defined, push the new value into the stack
array_push($this->_acl_ranks[$rankName]["RESOURCE"],$resource);

array_push($this->_acl_ranks[$rankName]["PERMISSION"],$permission);

return;

}

//add a resource to the resource stack
array_push($this->_acl_resource,$resource);

$rank = array(
"RANK" => $rankName,
"RESOURCE" => array(
$resource
),
"PERMISSION" => array(
$permission
)
);

//put the rank in the array stack
$this->_acl_ranks[$rankName] = $rank;

$this->_acl_count += 1;

return true;

}

function allow(){

return true;

}

//check if a grant access is located in the users array.
function check($resource,$user){

$rankName = $user['RANK'];

$offset = @array_search($resource,$this->_acl_ranks[$rankName]['RESOURCE']);

if(@array_key_exists($offset,$this->_acl_ranks[$rankName]['RESOURCE'])){

if($this->_acl_ranks[$rankName]['PERMISSION'][$offset] == "ALLOW"){

return true;

}

}

return false;

}

function deny(){

return true;

}

function inherit(){

return true;

}

}

and here is the implementation

//ACL TEST -defines
define("ANONYMOUS","ANONYMOUS");
define("BANNED","BANNED");
define("DELETED","DELETED");
define("USER","USER");
define("MODERATOR","MODERATOR");
define("ADMINISTRATOR","ADMINISTRATOR");

define("TEST",$_SERVER['PHP_SELF']);

$acl->add(TEST,ANONYMOUS);
$acl->add(TEST."?test=true",ANONYMOUS,"DENY");
$acl->add(TEST,BANNED,"DENY");
$acl->add(TEST,DELETED,"DENY");
$acl->add(TEST,USER,"ALLOW");
$acl->add(TEST,MODERATOR,"ALLOW");
$acl->add(TEST,ADMINISTRATOR,"ALLOW");



//ACL TEST -checks
$user = array(
"NAME" => "jamoy",
"RANK" => ANONYMOUS
);

if($acl->check($_SERVER['REQUEST_URI'],$user)){
echo '<h1>you are allowed</h1>';
}
else{
echo '<h1>you are not allowed</h1>';
}

i havent fully tested it yet, but it works pretty well with this implementation

thanks in advance....
