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();
?>
