本文实例讲述了php类的定义与继承用法。分享给大家供大家参考。具体如下：
<?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/>"."年龄：".$this->age; } function __tostring() { return "姓名：".$this->name."<br/>"."年龄：".$this->age; } function __destruct() { echo "<br/> I am dead！"; } function __call($key,$args) { echo "<br/>","你调用的方法名不存在：$key","<br/>"; echo "你调用的参数是：",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();?>希望本文所述对大家的php程序设计有所帮助。
