Fixed reference to object

[florisluiten]

The object referenced in the PHP doc is lowercased, but the actual class is camelCased. By using the same casing, we ensure that the IDE and any static analyzer understands the reference.

I'm happy to help, but I'm not comfortable singing the Contributor License Agreement. Especially since my fix is just one character.

Feel free to ignore my pull request. Perhaps you stumble on the same issue yourself, and find a solution for it.
