values
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(); $x->foo = true;
}
public function offsetGet($offset)
return $this->values[$offset];
public function offsetSet($offset, $value)
$offset
This check looks from parameters that have been defined for a function or method, but which are not used in the method body.
