New link – results off by 1我需要在一個表格中回顯給定日期每小時的條目數,即使它們是0.這似乎正在發生,但是以一種奇怪的方式…正如你所看到的,小時列不是在玩球這應該是0：00-1 …. 22.00-23.00等.預期的結果總數是19,當你將結果加在一起時也是正確的.到了我現在不知道腳本中發生了什么的地步,不知道從哪里開始修復格式問題.任何幫助非常贊賞

// Get list of times per hour for reader

$sqltimea = "SELECT CONCAT(Hour, ':00-', Hour+1, ':00') AS hours,

COUNT(r.readerid) AS tapcount

FROM

(

SELECT '0' AS Hour

UNION ALL SELECT '1' UNION ALL SELECT '2' UNION ALL SELECT '3'

LEFT JOIN taps t ON HOUR(t.`time`) = Hour

AND

DATE(t.time) = '2016-01-15' LEFT JOIN

ORDER BY Hour";

$qtimea = mysql_query($sqltimea);

// THE CHALLENGE! Put it in a table!

$hours = array("0:00-1:00", "1:00-2:00", "2:00-3:00", "3:00-4:00", "4:00-5:00", "5:00-6:00", "6:00-7:00", "7:00-8:00", "8:00-9:00", "9:00-10:00", "11:00-12:00", "12:00-13:00", "13:00-14:00", "14:00-15:00", "15:00-16:00", "16:00-17:00", "17:00-18:00", "18:00-19:00", "19:00-20:00", "20:00-21:00", "21:00-22:00", "22:00-23:00", "23:00-24:00");

for($i = 0; $i <= 23; $i++) {

while($timea = mysql_fetch_assoc($qtimea)) {

$tapsa = $timea['tapcount'];

echo "

" . $hours[$i] . "" . $tapsa . "";

}

}

?>

最佳答案 我不是PHP的專家,但你的i變量并沒有增加內部只需加上$hours [$i]或者只是從$timea [‘hours’]獲得你的標簽

你可能不需要初始化i = 0

while($timea = mysql_fetch_assoc($qtimea)) {

$tapsa = $timea['tapcount'];

$hour_label = $timea['hours'];

echo "

" . $hour_label . "" . $tapsa . "";

}
