PHP面向对象程序设计OOP继承用法入门示例

本文实例讲述了PHP面向对象程序设计OOP继承用法。分享给大家供大家参考，具体如下：

<?php class Person { var $name;//protected var $sex; var $age; function __construct($name = "", $sex = "男", $age = 22) { $this->name = $name; $this->sex = $sex; $this->age = $age; } function say() { echo $this->name . "在说话<br/>"; } function run() { echo "在走路·<br/>"; } } class Student extends Person { var $school; function __construct($name = "", $sex = "男", $age = 22,$school="") { parent::__construct($name,$sex,$age); $this->school = $school; } function study() { echo $this->name."正在".$this->school."学习<br/>"; } } class Teacher extends Student { var $wage; function teaching() { echo $this->name."正在".$this->school."教学，每月工资为".$this->wage."<br/>"; } } $teacher1 = new Teacher("kaifu","男",22); $teacher1->school = "edu"; $teacher1->wage = 4000; $teacher1->say(); $teacher1->study(); $teacher1->teaching(); ?>

结果：

kaifu在说话 kaifu正在edu学习 kaifu正在edu教学，每月工资为4000
