In Cake 3’s baked templates, I see this construction:

`$composition->has('composer') ?`

I’ve searched and I’ve googled (both in the cookbook and the internet at large), but I can’t find any documentation for “has()”. I’m guessing that this is some kind of synonym for property\_exists(), but I’d really like to see that spelled out somewhere. Can somebody point me to where this is explicitly defined?

I’m new to CakePHP 3 – please be gentle.
