PHP include_once fails without warning or error for an existing file

Question

Got me an error thats got me stumped. Am trying to implement a custom class loader in php. Am on version 5.6.11. The problem is that I am building up the path to a file dynamically and then doing an "include_once" on that path. PHP is just terminating execution at that point with no warnings or error messages. The path is valid. The code is basically like this

require_once "lib/includes/web/classloader/default.php";
require_once "lib/includes/web/controller/default.php";
$classloader = new web\classloaders\ClassLoader();
$controller_path = $classloader->registerController();
if($controller_path != null){
    require_once("$controller_path");
}

The file_exists and is_readable checks are done in the registerController() function of the class loader.

I have also tried this:

require_once $controller_path;

and this:

require_once($controller_path);

Any ideas?

There is no problem with the syntax as I tested with the code. The problem should be on the path. Try using echo $controller_path; die(); echo $controller_path; die(); before using require_once to see the path.

OR

You can insert

error_reporting(E_ALL); ini_set("display_errors", 1);

at the beginning of the PHP page to enable error display so that you can see what is causing the error..
