PHP学习笔记二十二【静态方法二】

<?PHP
class Student{
public static $fee;
public $name;
//构造函数
function __construct($name)
{
$this->name=$name;
}
//入学,静态方法无法操作非静态变量，因为静态方法（变量）是属于类，而非静态的成员变量时属于对象的
static    function  enterSchool($ifee)
{
self::$fee+=$ifee;
}
}
$student1=new Student("张三");
Student::enterSchool(100);
//$student1->enterSchool(100);
$student2=new Student("李四");
Student::enterSchool(100);
echo "<br/>总学费".Student::$fee;
?>
