That is known as passing by reference.  When you omit the '&', you are
actually making a copy of it instead of passing it directly to that
function or method.

This can be a problem with larger apps under heavy load, where you
accidentally have the webserver making copies of many arrays and
objects.

This behavior is changed by default in PHP5, and there are others on
this list that are much more knowledgable on PHP5 than I.  I'm still
trying to get Fedora Core 3 to install ;-)
