I've read a book, PHP DEVELOPER'S COOKBOOK, with great interest and it's a
great contribution to my bookcollection :-)
There is something I would like to know though....I have searched through
all my books and sites on PHP, but didn't find the answer....

In chapter 16 (Creating a Database-Independent API with PHP) there are some
functions written with a & in front of them.
Ex. in DB/standard.php; function &db_fetchall($args=array()){ ...

I've seen and used the pass by reference syntax on function parameters but
not on functionnames.
What effect does reference (&) have when used in front of the functionname??

It would help me a lot to get a fast answer.

Kind regards
