Little static trick to go around php strict standards ... Function caller founds an object from which it was called, so that static method can alter it, replacement for $this in static function but without strict warnings :) <?php error_reporting(E_ALL + E_STRICT); function caller () { $backtrace = debug_backtrace(); $object = isset($backtrace[0]['object']) ? $backtrace[0]['object'] : null; $k = 1; while (isset($backtrace[$k]) && (!isset($backtrace[$k]['object']) || $object === $backtrace[$k]['object'])) $k++; return isset($backtrace[$k]['object']) ? $backtrace[$k]['object'] : null; } class a { public $data = 'Empty'; function set_data () { b::set(); } } class b { static function set () { // $this->data = 'Data from B !'; // using this in static function throws a warning ... caller()->data = 'Data from B !'; } } $a = new a(); $a->set_data(); echo $a->data; ?> Outputs: Data from B !
