PHP Session Class return values -

i have simplet session class (below):

class session{      public static function init(){             @session_start();         }      public static function set($key, $value){             $_session[$key] = $value;     }      public static function get($key){       if (isset($_session[$key])) {         return $_session[$key];        } else if(empty($key)){         return $_session;        }      }      public static function destroy(){         session_destroy();     }   } 

to set single session value use

  session::set(name, value); 

to set multiple session value use

  session::set(name, array(name, value....)); 

then retrieve session require use:

  session::get(name); 

now problem when can set multi dimension values, cannot them current function above. how can re-structure get($key) not returns single request request

  session::set('joe', 'bloggs');   session::set('beth', array('age'=>'21','height'=>'5.5ft')); 

so instance again single session value eg joe:

    session::get('joe'); 

then if want beth's details can assign session value var , access inner details so:

   $age = session::get('beth');    $age['age'] 

but possible reconstruct method can do:

  session::get('beth','age'); 

or best stick doing.

thanks

you can update get method this:

public static function get($key, $item = null){     if (isset($_session[$key])) {         if(isset($item) && isset($_session[$key][$item])) {             return $_session[$key][$item];         }          return $_session[$key];     }       return null; //not found } 

then can use like:

session::get('joe'); // returns array session::get('joe', 'age'); // returns joe's age
