使用phpdbg调试codeigniter

Question

我正在尝试调试一个基于CodeIgniter (2.x)框架的web应用程序。我已经尝试了var_dumping $_SERVER，并在我的调试会话开始时重新创建了它(bootstrapping phpdbg)。

$ phpdbg -e index.php
phpdbg> ev require('boostrap.php');
phpdbg> run

然而，它给了我一个404。即使通过浏览器请求页面会给出正确的结果。谁能告诉我如何正确引导phpdbg，以便在codeigniter中加载正确的页面？这是我的引导代码，如果有帮助的话。

<?php
$_SERVER = array (
    'HTTP_USER_AGENT' => 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv: 38.0) Gecko/20100101 Firefox/38.0',

);
?>

Answer 1

好的，你可以在phpdbg cli中检查这个常量，看看它是否被定义了。你必须开始在codeigniter代码上创建中断..找到返回404的file:行，并在其中或之前添加一个分隔符，然后一步一步地执行，如果缺少某些内容，您将会找到答案。

如果您可以编辑框架本身的版本，一个可能的解决方案是查找所有引用输入法的行，并编辑这些行以接受一些伪造的调试常量。它会变成这样。然后，您可以在实际调试之前在phpdbg中使用ev设置常量。

system/core/Input.php:      return (!defined('DEBUGGING_FAKE_WEBREQUEST') AND (php_sapi_name() === 'cli' OR defined('STDIN')));
system/core/URI.php:            if (!defined('DEBUGGING_FAKE_WEBREQUEST') AND (php_sapi_name() == 'cli' or defined('STDIN')))
