PHP: Get list of private fields of a class (not instance!) -


how can iterate private fields of class without having instance of class name? get_object_vars requires existing instance.

using: reflectionclass

you can do:

class foo {   public    $public    = 1;   protected $protected = 2;   private   $private   = 3; }  $refclass = new \reflectionclass('foo'); foreach ($refclass->getproperties() $refproperty) {   if ($refproperty->isprivate()) {     echo $refproperty->getname(), "\n";   } }

or hide implementation using utility function/method:

/**  * @param string $class  * @return \reflectionproperty[]  */ function getprivateproperties($class) {   $result = [];    $refclass = new \reflectionclass($class);   foreach ($refclass->getproperties() $refproperty) {     if ($refproperty->isprivate()) {       $result[] = $refproperty;     }   }    return $result; }  print_r(getprivateproperties('foo'));  // array // ( //     [0] => reflectionproperty object //         ( //             [name] => private //             [class] => foo //         ) //  // )
