【中文标题】PHP 找不到 require_once 的文件，但它在那里？

【英文标题】：PHP cannot find file for require_once, but it's there?

【问题描述】：

这是MyBB中的一个错误，安装后我从索引中得到这个错误：

Warning: require_once(./global.php): failed to open stream: No such file or directory in C:\jws\htdocs\index.php on line 18

Fatal error: require_once(): Failed opening required './global.php' (include_path='.;C:\php\pear') in C:\jws\htdocs\index.php on line 18

顶部附近的索引代码：

require_once './global.php';
require_once MYBB_ROOT.'inc/functions_forumlist.php';
require_once MYBB_ROOT.'inc/class_parser.php';

文件在那里，我检查了文件夹。我没有更改文件中的任何内容。我使用的是 PHP 5.6.4，并且索引文件是从另一个文件中的 require_once 加载的。 这里：

<?php
$_SERVER = array(
"SERVER_PROTOCOL" => "HTTP/1.1","DOCUMENT_ROOT" => "C:/jws/htdocs","REMOTE_ADDR" => "127.0.0.1","REQUEST_URI" => "/","SERVER_SOFTWARE" => "JWS/1.0","argv" => "","REQUEST_TIME" => "Tue, 30 Dec 2014 12:33:14 PST","PHP_SELF" => "/","REMOTE_PORT" => "56601","REQUEST_METHOD" => "GET","SCRIPT_NAME" => "","SERVER_NAME" => "JWS/1.0","PATH_INFO" => "","ORIG_PATH_INFO" => "","argc" => "","GATEWAY_INTERFACE" => "N/I","SERVER_PORT" => "80","SCRIPT_FILENAME" => "C:/jws/htdocs/index.php","HTTP_ACCEPT_LANGUAGE" => "en-US,en;q=0.5","HTTP_HOST" => "127.0.0.1","QUERY_STRING" => "","REQUEST_TIME_FLOAT" => "1419971594194","HTTP_ACCEPT" => "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8","HTTP_USER_AGENT" => "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0","HTTP_ACCEPT_ENCODING" => "gzip, deflate","SERVER_ADDR" => "127.0.0.1","HTTP_CONNECTION" => "keep-alive",
);
$_GET = array(

);
$_POST = array(

);
$_COOKIE = array(

);
$_REQUEST = array(

);
require_once 'C:/jws/htdocs/index.php';
?>

【问题讨论】：

全局文件在同一个文件夹的哪里？？

@sanojlawrence index.php 和 global.php 在同一个 htdocs 文件夹中。

如果您需要将索引文件放入另一个文件中，则从它所在的位置（包含索引的文件）执行 require 语句

@Rizier123 我正在编写一个自定义网络服务器，我需要运行上面生成的代码，我该如何更改工作目录？

然后像这样替换并运行require_once 'global.php';

【参考方案1】：

用这个替换你的索引代码

require_once 'global.php';
require_once MYBB_ROOT.'inc/functions_forumlist.php';
require_once MYBB_ROOT.'inc/class_parser.php';

【参考方案2】：

我设法使用：

chdir("the path");

更改工作目录，我也遇到了服务器重定向失败的问题。

感谢您的帮助！

你不应该回答自己的问题

@sanojlawrence 是的，他是/可以！如果他自己想通了，他可以将他的解决方案分享给有同样问题的其他人！他也能接受自己的答案吗！

@Rizier123 如果他能回答自己的问题，那么提问有什么用

@sanojlawrence 分享解决方案！ （也看看这里，这个人解决了他的问题，2年后回答了！***.com/q/9260717/3933332）另外你可能想阅读帮助中心：***.com/help/self-answer

【参考方案3】：

顶部附近的index.php代码：

<?PHP
require_once MYBB_ROOT.'/global.php';
require_once MYBB_ROOT.'/inc/functions_forumlist.php';
require_once MYBB_ROOT.'/inc/class_parser.php';
?>

indexTest.php

<?php
