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