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

希望本文所述对大家PHP程序设计有所帮助。
