PHP Constructors

The important method is the __construct method.

class LinkedList { public $size = 0; public $head; function __construct($head = null) { $this->head = $head; if ($head != null) { $this->size = 1; } else { $this->size = 0; } } public function insertFirst($n) { if ($this->head != null) { $tmp = $this->head; $this->head = $n; $n->setNext($tmp); } else { $this->head = $n; } $this->size++; } public function getFirst() { return $this->head; } } class Node { private $data; private $next; function __construct($data = null) { $this->data = $data; } public function getData() { return $this->data; } public function setData($data) { $this->data = $data; } public function getNext() { return $this->next; } public function setNext($next) { $this->next = $next; } } $n1 = new Node(1); $n2 = new Node(2); $ll = new LinkedList($n1); $ll->insertFirst($n2);
