php類的定義與繼承用法執行個體_php技巧

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：

<?php/* * 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."<br/>"."年齡：".$this->age;  }  function __tostring() {    return "姓名：".$this->name."<br/>"."年齡：".$this->age;  }  function __destruct() {    echo "<br/> I am dead！";  }  function __call($key,$args) {    echo "<br/>","你調用的方法名不存在：$key","<br/>";    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 $this->getmessage();    echo '<br/>';    echo parent::getmessage();    echo '<br/>';    return "I am xinxin";  }  function getmessage() {    return "I am zilei getmessage <br/>";  }  function getff() {    echo "I am new getf";  } }$pp = new people("小弟","33");//$pp->name = "小明";//$pp->age = "88";echo $pp->name;echo '   ';echo $pp->age;echo '<br/><br/>';$xx = new xinxin("小小","13");echo $xx->getname();?>

希望本文所述對大家的php程式設計有所協助。
