Eric, This reply is too basic and is not the answer. The problem is more complex then you have grasped.

function ifsetor() { $args = func_get_args(); $count = count( $args ); for( $i=0; $i<$count; $i++ ) { if isset( $args[ $i ] )) {

      return $args[ $i ];

} return false; }

No, that doesn't address the problem. See this: ---------- 8< -------------------- 8< -------------------- 8< ---------- <pre> <?php function ifsetor() { $args = func_get_args(); $count = count($args); for ($i=0; $i<$count; $i++) {

       if (isset($args[$i])) {
           return $args[$i];
       }

} return false; } print ifsetor($x, $y, $z, "dante")."\n"; ?> </pre> PHP Notice: Undefined variable: x in .../ifsetor.php on line 13 PHP Notice: Undefined variable: y in .../ifsetor.php on line 13 PHP Notice: Undefined variable: z in .../ifsetor.php on line 13 ---------- 8< -------------------- 8< -------------------- 8< ---------- See my post regarding a specification for 'filled()' as a function. An important feature is that warnings about unset variables should not occur. Your suggestion does not qualify. This problem can not be solved in userspace. Dante
