如何禁用 select 選項值？

Question

如果從 while 循環中獲取值，如何禁用 select 選項值是否有其他方法可以解決此問題？

$qry = oci_parse($conn, "SELECT DATE_RES,TIME_RES FROM GYM_RESERVE GROUP BY DATE_RES, TIME_RES HAVING COUNT(*) >= 1");
oci_execute($qry);
while($row = oci_fetch_array($qry)){

}
<select>
     <option value='6'>06:00 - 07:00 am</option>
     <option value='7'>07:00 - 08:00 am</option>
     <option value='8'>08:00 - 09:00 am</option>
     <option value='9'>09:00 - 10:00 am</option>
     <option value='10'>10:00 - 11:00 am</option>
</select>

嗨看看下面的東西

$qry = oci_parse($conn, "SELECT DATE_RES,TIME_RES FROM GYM_RESERVE GROUP BY DATE_RES, TIME_RES HAVING COUNT(*) >= 1");
oci_execute($qry);
$i=0;
while($row = oci_fetch_array($qry)){
    $i++;
}
if ($i>0){
    $disable="disabled";
}
<select <?php echo $disable; ?>  >
