php - Define data members within constructor -

-

i have got little snippet of code, want able define each array element new data member.

class core_user {      protected $data_members = array(          'id'               =>  '%d',          'email'            => '"%s"',          'password'         => '"%s"',          'title'            => '"%s"',          'first_name'       => '"%s"',          'last_name'        => '"%s"',          'time_added'       =>  '%d' ,          'time_modified'    =>  '%d' ,          );      function __construct($id = 0, $data = null)     {         foreach($this->data_members $member){            //protected new data member         }      }

//protected new data member

you won't able create non-public property @ runtime. if protected paramount, can declare protected array or object , insert key/values in constructor
