php - 在里程表中添加多个前导零

Question

我尝试使用里程表进行奖励轮询，现在我希望我的号码轮询由零领先， 1,239,387是001,239,387，它从 123456789 开始。当里程表运行时，结果没有 00，只有 1,239,387。此代码我尝试使用 concat 或添加前缀以添加前导零。但如果领先 > 0 它显示

<?php 
$query="SELECT 
        CONCAT('00',MBR_ID) AS MBR_ID,
        NAME,
        RWD_DESC
FROM RTL.RWD_POLL RWD 
JOIN RTL.RWD_HEAD HED ON RWD.RWD_HEAD_NBR = HED.RWD_HEAD_NBR
WHERE HED.ACT_F = 1 AND RWD.DEL_NBR = 0
ORDER BY RWD_POLL_NBR DESC";
$result         = mysql_query($query);
$row            = mysql_fetch_array($result);
$MbrN           = $row['MBR_ID'];
$names          = $row['NAME'];
$reward         = $row['RWD_DESC'];
//$NoUndian = sprintf('%02d',$MbrN);
?>

<script>
setTimeout(function(){
 $('.odometer').html(<?php echo $NoUndian; ?> );
 }, 1000);
</script>

结果仍然是 1,239,387 没有零。
