php類的定義與繼承用法執行個體

本文執行個體講述了php類的定義與繼承用法。分享給大家供大家參考。具體如下： /* * class */ class people { public $name; public $age; function __construct($namec,$agec) { $this->name = $namec; $this->age = $agec; } protected function getmessage() { return "姓名：".$this->name." "."年齡：".$this->age; } function __tostring() { return "姓名：".$this->name." "."年齡：".$this->age; } function __destruct() { echo " I am dead！"; } function __call($key,$args) { echo " ","你調用的方法名不存在：$key"," "; echo "你調用的參數是：",var_dump($args); } final function getf() { echo "I am getf"; } } class xinxin extends people { function getname() { echo $this->getmessage(); echo ' '; echo parent::getmessage(); echo ' '; return "I am xinxin"; } function getmessage() { return "I am zilei getmessage "; } function getff() { echo "I am new getf"; } } $pp = new people("小弟","33"); //$pp->name = "小明"; //$pp->age = "88"; echo $pp->name; echo ' '; echo $pp->age; echo ' '; $xx = new xinxin("小小","13"); echo $xx->getname(); ?> 複製代碼 希望本文所述對大家的php程式設計有所協助。
