unlink ('/path/to/file');

Yes, in 2000 I was given a 20 minutes tutorial about PHP and webpages
by the chap doing the company's assets database; he then (having
resigned a little before) walked out the door and was not seen again.
Luckily for me I had 35 years of programming experience. That was my
intro to PHP, javascript, and how web servers work.

The best resource is the PHP web site; it's one reason I don't use
perl. PHP folks seem to do things in a straightforward way and don't
try to be smart-alecs.

See here for the docs:

<http://www.php.net/manual/en/>

You can find a simple example of how ajax can be used (how I use it in
my email client, f'rinstance) here:

<http://www.clothears.org.uk>

Anyway, keep coming back here with questions.
