Not true actually, it's a quick "if/else" using the ternary operator. It's also difficult to read all on one line: $ret_val = 0; if ($aday == $bday) { $ret_val = 0; } else { // what this does is test if $aday is less than $bday. // If so, it sets $ret_val to -1. If not, it sets $ret_val to 1. $ret_val = ($aday < $bday) ? -1 : 1; } return ret_val; HTH, John W
