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;
* Adds an offset to the LIMIT clause.
* @param int $offset
public function offset($offset)
throw new SimpleCrudException('Unable to add LIMIT offset because ENABLE_UPDATE_DELETE_LIMIT compiled option is disabled');
$this->offset = $offset;
