I taught myself PHP a few years ago and I use it frequently. Recently I
downloaded a PHP script built by somebody else, and came across this piece
of code:

$password = isset($HTTP_POST_VARS['password']) ? $HTTP_POST_VARS['password']
: '';

I have never seen the question mark or colon used in this way before. I
can't find any reference to it in my PHP book. Please tell me what it
means.
