"looped" function, how?

[SaMike]

So i've found that even if variable has no content isset($var) can still return true, so i made my own function is_set:

<?php
function is_set($var){
if(strlen($var) > 0){
	return true;
} else {
	return false;
}
}
?>

and it works fine. But for php's inbuild isset function, you can use it like this: if(isset($var1, $var2, $var3)) and i'd like to know if its possible to make my function work that too and if so, how?

Got it solved on my own:

function is_set(){
	$rf = false;
		$args = func_get_args();
  	foreach ($args as $arvo) {
    	if(strlen($arvo) > 0){
    		//do nothing
    	} else {
    		$rf = true;
    	}
  	}
  	if($rf){
  		return false;
  	} else {
  		return true;
  	}
}
