Hello,

This is my first time posting to the list... I hope this question is
not too silly, I am definitely not a guru at PHP.

Anyway, in one of my latest projects, I find myself using this bit of
code quite a bit:

if((isset($_REQUEST['sub'])) && (!empty($_REQUEST['sub']))) {
... code here...
}

Can I write a function that would make my life easier? Maybe something
like this (not tested):

//////// function security_check():
function security_check($x) {
$error = false;
if((isset($x)) && (!empty($x))) {
$error = false;
return $error;
} else {
$error = true;
return $error;
}
}

Or, is it perfectly valid and secure to use @, like so:

@... code here...

I know that it completely depends on the what one is trying to
accomplish in ones scripts, but any guidance and/or suggestions would
be greatly appreciated.

Thanks, I really appreciate your time.
Cheers,
Micky
