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:
http://www.php.net/manual/en/language.variables.variable.php
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".
