Euhm, I am not really sure what you mean. Like this?

For integers:
function
rand_number_without_certain_values_for_some_reason($start,$end,$not){
$i = 0;
do{
$i++;
if($i > 5000) return false;
$int = mt_renc($start,$end);
} while (is_array($not) && in_array($int,$not));
return $int;
}

Had to build in safety (the $i) to avoid endless looping when using
something like (1,4,array(range(1,4)))
