There are quite a few subtle and not so subtle differences between PHP 4 and PHP
5; enough that O'Reilly published a book called "Migrating to PHP 5", which I
found quite useful in making the transition. If you like the book you have, you
should try to find a more recent edition of that book and see if it helps. There
is very little to gain from learning a computer language from a book that is
over six years old, unless you specifically want to work with PHP 4, which as
you stated, you don't.
