Hi Ashim,
These are called Variable Variables. Ideally they should be avoided,
as they introduce unnecessary legibility issues.
This is what it does in a nutshell, it's actually quite simple:
$foo = 'bar';
$bar = 'foobar';
echo $$foo;//This prints foobar
What it does is, take the value of $
stripslashes() is rife with gaping security holes. For mysql
insertion rely on mysql_real_escape_string() or alternatively, you can
use prepared statements.
For outputting data on the page you should ideally be using
htmlspecialchars($var, ENT_QUOTES);
cheers,
Russ

I would stay clear of the ternary operator in nested coditions, for
obvious reasons. If it can fit in a single line and is essentially
clear in its message I dont see why not to use it.

Learning new languages open your mind to a whole new set of
possibilities. It also improves the way you code in your language of
choice. At this point in time, my goals are one language a year.
