I'm having the following issue when including a file that includes another file:
// path: /ajax/request.php
require_once("../classes/obj/Car.php");
// path: /classes/obj/Car.php;
require_once("Vehicle.php"); // superclass, this works
require_once("../exception/NoWheelException"); // this doesn't work when Car.php is require_once()'d from /ajax/request.php
the problem seems to be that if a file A
requires a file B
that requires files C
and D
, it only works if C
and D
are used without "../"
, or "./"
previous to the file name, when using require_once()
.
Is there any workaround or any ideas to fix this?
Use __FILE__
so you know where it's being included from:
require_once(dirname(__FILE__) . '/../exception/NoWheelException');
Where:
__FILE__ == "/classes/obj/Car.php";
dirname(__FILE__) == "/classes/obj";
Also, a note I didn't know - if your version of PHP is new enough, __DIR__
appears to be equivalent to dirname(__FILE__)
