php返回值計算公式？

$sql="SELECT COUNT(*) AS count FROM mark WHERE hID = '$hid'";

$result = mysql_fetch_array(mysql_query($sql));

$count = $result['count'];

$count++;

$numOfScore = $count;$count = mysql_result(mysql_query("SELECT COUNT(*) AS count FROM mark WHERE hID = $hid"),0);

$numOfScore = $count + 1;
