獲取子類的文件路徑

Question

要獲取子類的名稱，我使用get_called_class()。

我應該用什麼來獲取子類的文件路徑？

使用反射，特別是ReflectionClass::getFileName()。您如何實例化ReflectionClass完全取決於當前的範圍，如

// globally 
$reflectionClass = new ReflectionClass('SubClassName'); 

// within the sub class 
$reflectionClass = new ReflectionClass(__CLASS__); 

// within either sub or parent class in a static method 
$reflectionClass = new ReflectionClass(get_called_class()); 

// within either sub or parent class, provided the instance is a sub class 
$reflectionClass = new RelfectionObject($this); 

// filename 
$fn = $reflectionClass->getFileName(); 

// what I assume you mean by "path" 
$path = dirname($fn);
