用PHP解析类，函数和参数 [英] Parsing Classes, Functions and Arguments in PHP

问题描述

我想创建一个函数，该函数接收一个参数，该参数保存一个PHP文件的路径，然后解析给定的文件并返回如下内容:

I want to create a function which receives a single argument that holds the path to a PHP file and then parses the given file and returns something like this:

class NameOfTheClass
   function Method1($arg1, $arg2, $arg2)
   private function Method2($arg1, $arg2, $arg2)
   public function Method2($arg1, $arg2, $arg2)

abstract class AnotherClass
   function Method1($arg1, $arg2, $arg2)
   private function Method2($arg1, $arg2, $arg2)
   public function Method2($arg1, $arg2, $arg2)

function SomeFunction($arg1, $arg2, $arg3)

此函数应返回给定文件中存在的所有类，方法和函数，以及所有已定义的标识符(抽象，公共，私有，受保护，静态，扩展，接口等).

This function should return all the classes, methods and function that exist in the given file with all the defined identifiers (abstract, public, private, protected, static, extends, interfaces, ...).

我的第一个强项是使用正则表达式来执行此操作，但是它们在注释时的表现非常差，即:/*此函数返回(max(salary))*/，如果我想适当地支持范围，则变得非常复杂.

My first tought was to use regular expressions to do this, however these behave quite badly with comments, ie: /* this function returns(max(salary)) */ and become quite complex if I want to properly support scopes.

另一种可能的解决方案是使用以下内置的PHP函数:

Another possible solution was to use the following built-in PHP functions:

get_declared_classes
get_declared_interfaces
get_defined_functions
get_class_methods

但是这些函数不允许我查看定义了类/方法/函数的文件，因此它不是很有用.

However these functions don't allow me to see the file where the classes / methods / functions are defined and thus it's not very useful.

我相信Tokenizer扩展程序可以解决我的问题，但是我以前从未使用过此扩展程序.

I believe the Tokenizer extension is the solution for my problem, however I have never used this extension before.

推荐答案

如果您使用的是PHP 5，则 Reflection API 是您的工具.

If you are using PHP 5, the Reflection API is your tool.

示例:

$class = new ReflectionClass("NameOfTheClass");
$methods = $class->getMethods();
foreach($methods as $m) {
    print $m->name;
    $m->isPrivate() ? print "Private" : print "";
    $m->isPublic() ? print "Public" : print "";
    $params = $m->getParameters();
    foreach($params as $p) {
        print $p->getName();
        }
}
