如何包含包含的文件（包括嵌套包含）

Question

我試圖讓 SSI 為我的 SMF 論壇工作，但我這樣做的方式似乎與預期的方法不同。 我想include來自不同目錄的子目錄的SSI.php文件。 In other words, the SSI.php file is located at /home/account/public_html/forums/SSI.php and the file that says include SSI.php is at /home/account/public_html/dev/extension/page/file.php 。

如果我把include "/home/account/public_html/forums/SSI.php"; 我明白了

require_once(/QueryString.php): failed to open stream: No such file or
directory in '/home/account/public_html/forums/SSI.php line 64'

如果我把它作為相對路徑，我會得到同樣的結果。

我試過chdir和$_SERVER["DOCUMENT_ROOT"] ，結果相同。

SSI.php （出現錯誤的地方）的開頭是：

<?php

/**
 * Simple Machines Forum (SMF)
 *
 * @package SMF
 * @author Simple Machines http://www.simplemachines.org
 * @copyright 2011 Simple Machines
 * @license http://www.simplemachines.org/about/smf/license.php BSD
 *
 * @version 2.0.17
 */

// Don't do anything if SMF is already loaded.
if (defined('SMF'))
    return true;

define('SMF', 'SSI');

// We're going to want a few globals... these are all set later.
global $time_start, $maintenance, $msubject, $mmessage, $mbname, $language;
global $boardurl, $boarddir, $sourcedir, $webmaster_email, $cookiename;
global $db_server, $db_name, $db_user, $db_prefix, $db_persist, $db_error_send, $db_last_error;
global $db_connection, $modSettings, $context, $sc, $user_info, $topic, $board, $txt;
global $smcFunc, $ssi_db_user, $scripturl, $ssi_db_passwd, $db_passwd, $cachedir;
global $image_proxy_enabled, $image_proxy_secret, $image_proxy_maxsize;
global $auth_secret, $cookie_no_auth_secret;

// Remember the current configuration so it can be set back.
$ssi_magic_quotes_runtime = function_exists('get_magic_quotes_gpc') && get_magic_quotes_runtime();
if (function_exists('set_magic_quotes_runtime'))
    @set_magic_quotes_runtime(0);
$time_start = microtime();

// Just being safe...
foreach (array('db_character_set', 'cachedir') as $variable)
    if (isset($GLOBALS[$variable]))
        unset($GLOBALS[$variable]);

// Get the forum's settings for database and file paths.
require_once(dirname(__FILE__) . '/Settings.php');

// Make absolutely sure the cache directory is defined.
if ((empty($cachedir) || !file_exists($cachedir)) && file_exists($boarddir . '/cache'))
    $cachedir = $boarddir . '/cache';

$ssi_error_reporting = error_reporting((defined('E_STRICT') ? E_ALL | E_STRICT : E_ALL) & ~E_DEPRECATED);
/* Set this to one of three values depending on what you want to happen in the case of a fatal error.
    false:  Default, will just load the error sub template and die - not putting any theme layers around it.
    true:   Will load the error sub template AND put the SMF layers around it (Not useful if on total custom pages).
    string: Name of a callback function to call in the event of an error to allow you to define your own methods. Will die after function returns.
*/
$ssi_on_error_method = false;

// Don't do john didley if the forum's been shut down competely.
if ($maintenance == 2 && (!isset($ssi_maintenance_off) || $ssi_maintenance_off !== true))
    die($mmessage);

// Fix for using the current directory as a path.
if (substr($sourcedir, 0, 1) == '.' && substr($sourcedir, 1, 1) != '.')
    $sourcedir = dirname(__FILE__) . substr($sourcedir, 1);

// Load the important includes.
require_once($sourcedir . '/QueryString.php');
require_once($sourcedir . '/Subs.php');
require_once($sourcedir . '/Errors.php');
require_once($sourcedir . '/Load.php');
require_once($sourcedir . '/Security.php');

File.php要簡單得多，包括：

<?php 
include "/home/account/public_html/forums/SSI.php"; 
echo $sourcedir;
?>

由於此代碼將用於各種不同的安裝，並非所有安裝都允許編輯SSI.php ，因此我希望有一種無需編輯即可使其工作的方法SSI.php 。 任何東西都可以放在file.php中。

編輯：不是權限問題。 isreadable() 對所有三個文件都返回 true，我可以毫無問題地對它們 append。

看來您在已經包含使用相對路徑的文件中使用了require / require_once ，因此解決方案是使用絕對路徑。

注意： __DIR__常量將是定義文件絕對路徑的好方法，如果在include中使用，請參見

所以嘗試將$sourcedir更改為__DIR__因為參考您提到的錯誤消息（ require_once(/QueryString.php) ）， $sourcedir是空的。

例如：如果SSI.php和QueryString.php在同一目錄中，請嘗試更改：

require_once(__DIR__ . '/QueryString.php');

與其他require / include文件相同的東西
