Challenge 1 / 4

Check out this Koala class:

namespace Animal\Adorable;

class Koala
{
}

And this code that uses it:

$koala = new \Animal\Adorable\Koala();

Is that first slash in \Animal\Adorable\Koala necessary?

Yes. If you choose to not have a use statement, then you must always start with a \ so that PHP knows to build the namespace from the root of all namespaces.

No. The slash is always optional, and really redundant: PHP knows that you are looking for a class from the root of the namespace.

It depends on whether or not this file lives in a namespace.
