Instanceof and namespaces

Question

I am facing an unexpected behaviour trying to use the following:

$object instanceof $class

1/ PHP \'instanceof\' keyword and namespaces wor

Answer 1

You can test for instances using namespaces, but use the fully qualified class name.

For your test I would do this:

$class = "\\Tools\\Tests\\Entity\\testObject";
$object = new $class;
var_dump($object instanceof $class); //bool(true)

You can also test this way using single quotes and not worry about escaping your backslashes and save yourself a few keystrokes.

$class = '\Tools\Tests\Entity\testObject';
$object = new $class;
var_dump($object instanceof $class); //bool(true)
