class B extends A
{
public static function _test(){
return 'B_result';
}
}
class C extends A
{
public static function _test(){
return 'C_result';
}
}
class A
{
public static function test(){
$result = static::_test();
echo get_called_class();
echo $result;
}
}
$sClass = 'C';
$sClass::test();
output:C
$result:C_result
雖然看似簡單，但是如果_test()算出來的結果不是那麼的規律，而且$sClass這邊又不是寫的這麼直觀。可以用get_called_class()來找到A::test()的static::_test()是呼叫哪個Class的_test()
