我上课了
Class User {
private $_name;
private $_email;
public static function factory() {
return new __CLASS__;
}
public function test() {
}
}
User::factory();
它会引起我以下语法错误.
Parse error: Syntax error,unexpected T_CLASS_C in htdocs/test/index.PHP on line 8
因为Static factory()方法在静态方法调用期间无法创建对象,所以会抛出错误.
当我将魔术常数__CLASSS__更改为当前类的名称,即用户,那么它可以工作.
我失踪了什么
尝试：
Class User {
private $_name;
private $_email;
public static function factory() {
$class = __CLASS__;
return new $class;
}
public function test() {
}
}
