Hiya,
> What do they do? No idea.
In a few lines, they are/do (roughly cut) the following:
PHP = a scripting language. It is used to generate HTML, often
dynamically, based on what is e.g. read out of a database or files (as
is the case in e.g. TOPE).
MySQL = a (relational) database. Used to store and retrieve the data itself.
Apache = webserver software. This is basically the software that makes
sure that all webbrowser requests to scripts, HTML pages, images, etc.
are 'handled' properly. E.g., for PHP files this means that Apache will
make sure the proper interpreter is called on them, and that the output
is sent back to the browser.
The three of those tend to comprise a 'typical' PHP server set-up. Note
that MySQL is not stiectly necessary, and that for all of these three
alternatives exist. The above combination is very powerful, flexible and
hence highly popular though.
The reason why your book doesn't mention it, is probably that the author
assumed that the people interested in these technologies will already
have had a little introduction (like what I typed above to what each
component is. Having said that, it would have been little trouble to add
a small section about it.
Cheers!
