I'm a beginner in php.
i noticed that a lot of codes (actually all of them)
use
$_POST['something']
to get something form the $_POST array
while i simply use this method
$something
i know it's minor stuff and doesn't actually matters..
but it keeps confusing me whether i should use this or that.. and some times (when I'm really confused) i use them both!!
so i just want to know the proper way of this.. and why?
