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(); $x->foo = true;
if ($condition !== null && $condition !== false) {
return $this->eval->getReturn($args[1]);
} else {
return isset($args[2]) ? $this->eval->getReturn($args[2]) : $this->newReturnType('Nil');
