PHP interface problem - class not found

Question

Hi I have a very simple class that implements an interface. Both the class and the interface are in the same file.

When I implement the interface I get a fatal error "Class not found", but when I remove the implements and then try to use the class I can use it fine???

Can anyone offer any advice on this?

Sorry here is some code that I am using to test at the moment:

$tester = new TypeOneTester();
$tester->test("Hello");

interface iTestInterface
{
    public function test($data);
}

class TypeOneTester implements iTestInterface
{
    public function test($data)
    {
        return $data;
    }
}

Answer 1

Create an instance of your class after the class and the interface are defined, not before.

The order of definition in this case should be:

1. Interface
2. Class
3. Instance of Class (objects)

Answer 2

smells like a bug in php. Make sure it's reproducible with the latest version and post to bugs.php.net.

Reproduce code

interface I {}

$a = new A;
$b = new B;

class A {
    function __construct() { echo 'A'; }
}

class B implements I {
    function __construct() { echo 'B'; }
}

Expected

AB

Actual:

A
Fatal error: Class 'B' not found...
