如何在 PHP5 对象中查找注释? [英] How to find annotations in a PHP5 object?

问题描述

我希望能够在我的 PHP5 对象中实现自定义注释，并且我想通过构建我自己的解析器来了解整个过程是如何工作的.

I would like to be able to implement custom annotations in my PHP5 objects, and I'd like to learn how the whole process works by building my own parser.

不过，首先，我需要知道如何查找注释.

To start, though, I need to know how to FIND the annotations.

是否有我缺少的反射方法，或者还有其他方法吗?

Is there a Reflection method that I am missing, or is there another way?

例如，我希望能够在类中找到以下注释:

For example, I'd like to be able to find the following annotation in a class:

/**
 * @MyParam: myvalue
 */

推荐答案

您可以使用 ReflectionClass::getDocComment，例如:

You can do this using ReflectionClass::getDocComment, example:

function getClassAnnotations($class)
{       
    $r = new ReflectionClass($class);
    $doc = $r->getDocComment();
    preg_match_all('#@(.*?)\n#s', $doc, $annotations);
    return $annotations[1];
}
