What's the difference between:
if($var)
and
if(isset($var))
First is checking if $var is true (1, true, has value) or false (0, false, null, not set, etc.). Second is checking if $var has been defined, regardless of value. Depending on your error reporting level, the first one will throw a notice if $var has not been defined.
