require_once :failed to open stream: no such file or directory

Question

I have this testing code in \"PAGE A\":

Answer 1

set_include_path(get_include_path() . $_SERVER["DOCUMENT_ROOT"] . "/mysite/php/includes/");

Also this can help.See set_include_path()

Answer 2

It says that the file C:\wamp\www\mysite\php\includes\dbconn.inc doesn't exist, so the error is, you're missing the file.

Answer 3

You will need to link to the file relative to the file that includes eventManager.php (Page A)

Change your code from
require_once('../includes/dbconn.inc');

To
require_once('../mysite/php/includes/dbconn.inc');

Answer 4

this will work as well

 require_once(realpath($_SERVER["DOCUMENT_ROOT"]) .'/mysite/php/includes/dbconn.inc');

Answer 5

The error pretty much explains what the problem is: you are trying to include a file that is not there.

Try to use the full path to the file, using realpath(), and use dirname(__FILE__) to get your current directory:

require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));
