Thanks. The word Reference was what was missing, as was the term "de-ref".

Read a bit further down in the above link, namely the php link, which is:

Using the term "de-ref is not complete and could be misleading -- dereferencing a variable in php is simply $$var and not ->var.

The "arrow operator" ($a->$b) dereferences the element to its left and accesses the member to it's right. If you want an example in C it would be (*a).b

While I was not able to find the "official" name for the operator, but it could be called an "dereference access operator" or the "field access operator".
