确定在PHP类文件中定义的类 [英] Determining what classes are defined in a PHP class file

问题描述

由于我们项目中的每个PHP文件都包含一个类定义，我如何确定在文件中定义什么类或类？

Given that each PHP file in our project contains a single class definition, how can I determine what class or classes are defined within the file?

我知道只是regex文件 class 语句，但我更喜欢做更有效的东西。

I know I could just regex the file for class statements, but I'd prefer to do something that's more efficient.

推荐答案

我需要这样一个项目，我正在工作，这里是我写的功能：

I needed something like this for a project I am working on, and here are the functions I wrote:

function file_get_php_classes($filepath) {
  $php_code = file_get_contents($filepath);
  $classes = get_php_classes($php_code);
  return $classes;
}

function get_php_classes($php_code) {
  $classes = array();
  $tokens = token_get_all($php_code);
  $count = count($tokens);
  for ($i = 2; $i < $count; $i++) {
    if (   $tokens[$i - 2][0] == T_CLASS
        && $tokens[$i - 1][0] == T_WHITESPACE
        && $tokens[$i][0] == T_STRING) {

        $class_name = $tokens[$i][1];
        $classes[] = $class_name;
    }
  }
  return $classes;
}
