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:
name = $name;
$this->sex = $sex;
$this->age = $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);
