本文實例講述了PHP物件導向程式設計OOP繼承用法。分享給大家供大家參考，具體如下：
<?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();
?>結果：
kaifu在说话 kaifu正在edu学习 kaifu正在edu教学，每月工资为4000
