data
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(); $x->foo = true;
}
* Get the current element
* @return mixed
public function current() {
return current($this->data);
* Return the current key
* @return string|int
public function key() {
return key($this->data);
* Move to next element
public function next() {
return next($this->data);
* Check if element is valid (isset)
* @return boolean
public function valid() {
return isset($this->data[$this->key()]);
