*Great* advice! One very common beginner mistake is to make a whole
host of changes at once, before trying to execute the result. When (not
if) problems occur, that makes it difficult to pin down exactly which
one of the many changes is responsible. Keeping changes as small as
possible, and testing in between each, makes it easier.

Ouch. It's far better, IMHO, to use a SCM (source code management) tool
that's been expressly designed for just that purpose, such as Subversion,
Mercurial, or Git. Making backup copies (i.e. foo.php, foo-2.php, foo-
bak.php, foo-ihopethisdoesntbreak.php, etc.) is a pretty poor substitute
for such a tool.
