从扩展类php获取函数名称

Question

Hi I do not speak English (google translator) apologize for the translation, I want to do something like this:

class First_class extends Second_class
{
   function first_class_function ()
   {
   echo $this->second_class_function ();
   }
}

class Second_class
{
   function second_class_function ()
   {
   return "function name which call this function" // in this case first_class_function
   }
}

Is that possible?

Answer 1

Yes this is possible, use the constant variable __FUNCTION__ or __METHOD__ , this will give you the function name that you used, as you are using a class I'd recommend using the METHOD constant.

function second_class_function () {
    return __METHOD__;
}

Answer 2

您可以使用debug_backtrace函数： http ://php.net/manual/en/function.debug-backtrace.php
