validKeys
In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:
class MyClass { } $x = new MyClass(); $x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:
class MyClass { public $foo; } $x = new MyClass(); $x->foo = true;
}
* Setter for validKeys
* @param array $validKeys
public function setValidKeys(array $validKeys)
$this->validKeys = $validKeys;
