PHP how can I find out right properties within Object -

class {     public $a = "3";     public $b = "0";     public $b = "3";     public $c = "0";     public $d = "0";     public $e = "0";     public $g = "0"; } 

how can find out properties greater zero?

you can use get_class_vars function outside object that:

$a = new a();  $class_vars = get_class_vars(get_class($a));  foreach ($class_vars $name => $value) {     if ($value > 0) {          echo "$name : $value\n";     } }
