I have Folder Home with two subfolders like the following

+Home  
 +include  
   - membersite_config.php

+iDiscover  
   -index.php

in index.php I added the require_once script to access membersite_config.php

<?PHP

require_once($_SERVER['DOCUMENT_ROOT'].'/include/membersite_config.php');
?>

I get the following error : Warning: require_once(./include/fg_membersite.php): failed to open stream: No such file or directory in D:\Home\include\membersite_config.php on line 2
Fatal error: require_once(): Failed opening required './include/fg_membersite.php' (include_path='.;C:\php\pear') in D:\Home\include\membersite_config.php on line 2

The error says No such file or directory while the The path "D:\Home\include\membersite_config.php" is correct . When I move index.php to be under the root , the page works well.

I also tried to use the following code as described here but it gives the same error

<?PHP


define('ROOT', 'D:Home\\');
require_once(ROOT ."/include/membersite_config.php");
?>

Edit :

I too tried require_once("../include/membersite_config.php"); And it gives the same error

Thanks in advance

回答1:

You must include like this

require_once(dirname(__FILE__) . '/include/membersite_config.php');

Because DocumentRoot can be not set in httpd.conf

回答2:

The error means that you have a require in your membersite_config.php that does not work on line 2.

回答3:

require_once(dirname(dirname(__FILE__)).'/home/include/membersite_config.php');

回答4:

Try this:

require_once("../include/membersite_config.php");

don't forget to check the file/folder permissions!

回答5:

Try this:

<?PHP
require_once('../include/membersite_config.php');
?>

回答6:

'..' means back

require_once('../include/membersite_config.php');

means get out the folder you are in, then enter include...

if you have to get out three folders do this ../../../include... etc.

回答7:

For debugging try this:

<?php
$dir_files=glob($_SERVER['DOCUMENT_ROOT'].'/include/*');
print_r($dir_files);
?>

after you run this script, you will see if your filename(s) are correct.
