如何包括具有包含包括嵌套包含的文件

编程问答 2022-08-17

问题描述

我正在尝试让SSI在我的SMF论坛上工作，但是我的操作方式似乎与预期的方法不同。我想从另一个目录的子目录中include SSI.PHP文件。换句话说，SSI.PHP文件位于/home/account/public_html/forums/SSI.PHP，而表示include SSI.PHP的文件位于/home/account/public_html/dev/extension/page/file.PHP。

如果我放include "/home/account/public_html/forums/SSI.PHP";，我会得到

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

如果将其作为相对路径，我将得到相同的结果。

我尝试过chdir和$_SERVER["DOCUMENT_ROOT"]，但结果相同。

SSI.PHP（显示错误的地方）的开头是：

<?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($sourcedir,1) == '.' && substr($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要简单得多，包括以下内容：

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

由于此代码将用于各种不同的安装中，并非所有安装都允许编辑SSI.PHP，所以我很想一种无需编辑SSI.PHP就可以使其工作的方法。一切都可以放在file.PHP中。

编辑：不是权限问题。对于所有三个文件来说，isizable（）都返回true，我可以毫无问题地附加到它们上。

解决方法

似乎您正在使用已经包含相对路径的文件内部使用require / require_once，所以解决方案是使用绝对路径。

NB ：如果在__DIR__ see

内部使用include常量将是定义文件绝对路径的好方法。

因此，请尝试将$sourcedir更改为__DIR__，因为参考您提到的错误消息（require_once(/QueryString.php)），$sourcedir为空。

例如：如果SSI.php和QueryString.php在同一目录中，请尝试更改此内容：

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

与其他require / include文件相同的事情
