PHP如何获取带有类和名称空间路径作为字符串的方法名称? [英] PHP How to get a method name with a class and namespace path as a string?

问题描述

我真的很讨厌写这个问题，因为我有点研究人员"，而且，我总是能找到我要寻找的东西……但是这个人让我很烦，我找不到答案无处不在...所以，就这样:

I really hate to write this question because I'm kind-of "research guy" and, well, I always find what I'm searching for... But this one bugs me a lot and I can't find the answer anywhere... So, here it goes:

正如标题所述，我需要获取一个方法名称，该方法名称的结尾类和名称空间路径为字符串.我的意思是这样的:"System \ Language \ Text :: loadLanguageCache" .众所周知，您可以通过键入以下内容来获得一个类名(具有完整的命名空间路径):即 Text :: class 并返回"System \ Language \ Text" ，但是有一种方法可以解决这个问题吗?类似于: Text :: loadLanguageCache :: function 以获取字符串:"System \ Language \ Text :: loadLanguageCache" ?

As the title says I need to get a method name with the trailing class and namespace path as a string. I mean something like this: "System\Language\Text::loadLanguageCache". As we know, you can get a class name (with full namespace path) by typing, i.e.: Text::class and it returns "System\Language\Text", but is there a way to get this for a method? Something like: Text::loadLanguageCache::function to get string: "System\Language\Text::loadLanguageCache"?

我想我应该进一步解释...我知道魔术常量 __ METHOD __ ，但是问题是它在被调用方法内有效 ，我需要这个方法之外" .以这个为例:

I think I should explain this further... I know about magic constant __METHOD__ but the problem is that it works inside the called method and I need this "outside the method". Take this as example:

//in System\Helpers
function someFunction()
{ return __METHOD__; }

如果我调用要获取的函数，就可以了(假设方法在 System \ Helpers 类中)-"System \ Helpers :: someFunction" .但是我想要的是这样:

That's all OK with this if I call the function I'll get (let's assume that method is in System\Helpers class) - "System\Helpers::someFunction". But what I want is this:

//in System\Helpers
function someFunction()
{ //some code... whatever }

// somewhere not in System\Helpers
function otherFunction()
{
    $thatFunctionName = Helpers::someFunction::method //That imaginary thing I want

    $thatClassName = Helpers::class; //this returns "System\Helpers"
}

我希望这可以使我的问题稍微有所一点:)

I hope this cleared my question a bit :)

推荐答案

您必须使用魔术常数，您可以在

You must use the magic constant, you can read more about at Magic constants in php.net

__METHOD__

在课程之外，您必须使用 Reflection ，具体说明请参见 ReflectionClass 文档:

Outside of the class you must use Reflection as is explained at ReflectionClass documentation:

<?php
$class = new ReflectionClass('ReflectionClass');
$method = $class->getMethod('getMethod');
var_dump($method);
?>;

返回:

object(ReflectionMethod)#2 (2) {
  ["name"]=>
  string(9) "getMethod"
  ["class"]=>
  string(15) "ReflectionClass"
}
