note 116519 added to function.isset

Am trying to create a 'generic is_set function' that i can pass any either a variable or multi-variables or an array and will return true if what is passed to it is set and false if what is passed to it false. This is what i came up with but. function is_set () { if(func_num_args() == 1 && is_array (func_get_arg(0))){ $arr = func_get_arg(0); $c = count($arr); for($i = 0; $i < $c; $i++){ if (!isset($arr[$i])) return false; } return true; } elseif(func_num_args() == 1 && !is_array (func_get_arg(0))) { $arg = func_get_arg(0); return (isset($arg)) ? true : false; } else{ $args = func_get_args(); for($i = 0; $i < count($args); $i++){ if (!is_set($args[$i])) return false; } return true; } } pls email me for any correction.
