Thread: Session arrays in class

Hey guys, here's a little problem for you, I need to be able to set and get session values from with a class by calling a function, not a problem however some of the session variables will be arrays

e.g.

PHP Code:

$_SESSION['basesession']['is_admin'] = 1;
$_SESSION['basesession']['page_access'][] = 'index';
$_SESSION['basesession']['page_access'][] = 'mydetails';
$_SESSION['basesession']['admin_details']['title'] = 'Mr'; 


As you can see page_access is an array which I would need to be able to do for loops with and check for in_array as well but I cant figure out how to do it.

PHP Code:

function get($VALUE){
  if (!is_array($VALUE)){
    return $_SESSION['basesession'][$VALUE];
  } else {
    foreach ($VALUE as $key=>$val){
      $test .= '['.$key.']';
    }
    return ($_SESSION['basesession'].$$test);
  }
} 


That's the get function I made to get the values which doesn't work, a print_r($_SESSION) prints the following code
Session Dump

Code:

Array
(
    [basesession] => Array
        (
            [is_logged_in] => 1
            [page_access] => Array
                (
                    [0] => index
                    [1] => mydetails
                )
            [admin_details] => Array
                (
                    [title] => Mr
                )
        )
)

Well I managed to solve this one myself, for anyone who wants the functions they are listed below.

PHP Code:

    function get($KEY){
        if (strpos($KEY, ':')){
            // it will be an array
            $fields = explode(':', $KEY);
            $eval = '$_SESSION[\'user_login_manager\']';
            for ($i = 0; $i < count($fields); $i++){
                $eval .= '[\''.$fields[$i].'\']';
            }
            eval("\$thevar = ".$eval.";");
            return $thevar;
        } else {
            return $_SESSION['user_login_manager'][$KEY];
        }
    }

    function set($KEY, $VALUE){
        if (strpos($KEY, ':')){
            $eval = "\$_SESSION['user_login_manager']";
            $fields = explode(":", $KEY);
            for ($i = 0; $i < count($fields); $i++){
                if (strlen($fields[$i]) > 0)$eval .= "['".$fields[$i]."']";
                else $eval .= "[".$fields[$i]."]";
            }
            if (is_string($VALUE))$eval .= " = '".$VALUE."';";
            else $eval .= " = ".$VALUE.";";
            
            echo "<i>".$eval."</i>\n";
            eval($eval);
        } else {
            $_SESSION['user_login_manager'][$KEY] = $VALUE;
        }
    }

//usage
// to set $_SESSION['user_login_manager']['test']
set('test', 'value');
set('var1:var2', 'value');//['user_login_manager']['var1']['var2']
set('var1:', value);//['user_login_manager']['var1'][]
