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(); $x->foo = true;
if ($child instanceof RendersEmptyVariables) {
$allEmpty &= $child->rendersEmptyVariables($data);
}
return boolval($allEmpty);
