require_once文件来自另一个需要的目录

This is a big confusing but I'll try to be as clear as possible.

I am using the Starter Site PHP Template in Web Matrix for an assessmnent, now when I move several files such as the files containing the database details, header, footer ect.. into the admin file I am having an issue with my index.php and page.php.

These files use require_once() to include several files within the admin folder. However in the admin folder the files being required have require_once tags again within that directory.

When I use require_once('admin/database.php'); the database file has require_once(somefile.php) within it. There are numerous files like this being included.

How can I use include these files using require_once in the root directory without getting errors like these.

warrning: require_once(/Includes/simplecms-config.php): failed to open stream: No such file or directory in C:\xampp\htdocs\starter-ste\admin\Includes\connectDB.php on line 2

The includes folder is located within the /admin/ folder.

php require statements will look for files in the current directory and directories in the php_include_path. You can solve your problem by adding your include directories to include path.

You can do this dynamically by calling set_include_path

$directories = array('/library', 'var/', get_include_path());

set_include_path(implode(PATH_SEPARATOR, $directories));

[EDIT] Your server might not know where the root directory of the website is. So, first, get the document's root directory and append it to the file name like this:

$root = realpath($_SERVER['DOCUMENT_ROOT']);
require_once "$root/your_file_path_here";

Looks like you haven't enclosed the file name within quotes. So that line should probably be like this:

require_once("/Includes/simplecms-config.php");
