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(); $x->foo = true;
}
* Return the current element.
* @return mixed
public function current()
return current($this->container);
* Return the key of the current element
public function key()
return key($this->container);
* Move forward to next element.
public function next()
next($this->container);
* Checks if current position is valid.
* @return boolean
public function valid()
return current($this->container) !== false;
