[RESOLVED] Avoid notice in a isset function.

[whisher06]

Hi.
I need a function as shortcut of this
code:

echo isset($var)?$var:'';

I tried this but I've got a notice:

function _($var=''){
	return isset($var)?$var:'';
}

Do you know a way to avoid notice ?

Bye.

function my_isset(&$var){  // pass variable by reference with "&"
    return isset($var)?$var:'';
}
echo my_isset(@$xyz); // use "@" to suppress notice if var is undefined

Good idea quick and quite dirty but it works 😉
Thanks a lot.

Bye.
