use class from namespace in php in class method

I'm new to php and trying to use namespaces for the first time and I have this crazy problem in a big php file (simplified below):

B.php:

namespace Logic;

class C {}
class B {}

A.php:

use Logic\C;

class A extends \BaseClass {
    public function __construct() {}
    // [...500 lines of code...]
    private function hi() { $c = new C(); }
}

The hi method gives the error: Class 'Logic\\C' not found in A.php

But if I just reference B in the constructor of A, it works as expected:

class A extends \Base {
    public function __construct() { $dummy = new C(); }
    // [...500 lines of code...]
    private function hi() { $c = new C(); }
}

When the hi method in the modified code above is run, there are no problems.

Can anybody think of a reasonable explanation for why this happens? Am I misusing namespaces in php?

You need to understand, that the use statement doesn't automatically include the source code file where Logic\C is defined. You need to use an autoloader, or manually require_once that file before accessing classes from that file.

I suggest to follow the manual about namespaces (and the examples there): http://php.net/manual/en/language.namespaces.php
