90% of what your book covers should be fine in 4.4.2. there have been many
functions added (like get_file_contents) that didn't exist prior to 5 and,
some parameters have been added to others (like print_r...new param allows
the output to be assigned to a variable or as inline output.
the major things that won't work are classes. in php 5, there is a real,
live constructor and other methods like __clone, __copy, etc.. any
constructor will have to be renamed to the name of the class object. also,
scope definitions are new to 5 (private, public, static, etc.). and the
final "big one"...php 5 passes variables by reference rather than by
value...the opposite of previous versions.
i'd say, if you've got broadband, install your stuff on your pc and re-route
your domain traffic to your pc...but that's just me. ;^) that may not be an
option though, if you're working for someone else. if you just want to learn
though...run it on your pc and simply browse http://localhost/
good luck.
