Just use empty() ?!
With error_reporting(E_ALL) you'll get a bunch of warnings if you only use
empty() w/o the isset() !
use isset() first and then check wheter empty o
first.

Because sometimes you just want to check if something is set due to null,
'' and 0 being important.
$var = '';
empty($var); // evaluates to true
isset($var); // evaluates t
But if this is true what you say, that empty() checks for
not set
null
an empty string
zero
Why would i ever want to use isset() then?
If i understood you correctly, would the following
op = isset($_GET['op']) && !empty($_GET['op']) ? $_GET['op'] : '';
be the same as
op = !empty($_GE

Yes. Just use empty(). It automatically checks if the variable is:
not
I have wrote this function:
function issne($var)
{
return isset($var) && !empty($var) ? true : false;
}
which can be called as: if (issne(&$mightbeundefinedvariable)) echo "using
this variable";
is there is any builtin function that does that? (one function call).
