PhP Namespaces in input types

Question

I have the following oddity in our development enviroment. Lets say i have 2 classes one is in namespace \wtf

namespace \wtf\isWrongHere;

class DrStrange {

}

And i have an other class wich i am passing the class via dependency injection

 namespace \normalPpl;


     class ThisHasNoLogic {
       public function __construct(DrStrange $strange){ 
           //here be dragons
       }
     }

Now when i instanziate the class via:

$whata = new ThisHasNoLogic(new \wtf\isWrongHere\DrStrange());

On My dev debian machine i get normal instance, on our dev machine(a clone of our live server) i get normall results to.

BUT on our live machine i get a fatal error. How is that possible?

PHP Catchable fatal error: Argument 2 passed to xxxx must be an instance of xxxxx, instance of aaaaar given, called in ....QQ

In all servers it is acepting the input type but on live it dous tel me tht the class passed dous not match the required...

aka \wtf\isWrongHere\DrStrange ist not a instance of DrStrange, wich is just plain WTH@12 moment for me.

Here are the specs:

I dont know what to do to make the test server behave like the Live. Anyone any sugesstions??

UPDATE:

When i use the:

use \wtf\isWrongHere\DrStrange;

It works. But i have no way to reproduce it on the test systems which are ignoring this error. i want to replicate it on a diferent machine. Tht is my actual problem which is pleguing my team for over 1 year.

You have to give the DrStrange namespace to have it work.

namespace \normalPpl;

use wtf\isWrongHere\DrStrange;

 class ThisHasNoLogic {
   public function __constructor(DrStrange $strange){ 
       //here be dragons
   }
 }

Given you have a good autoload (see psr-4 or php spl_autoload )
