php - 使用 mysql 、php 根据日期范围检索数据

Question

我正在 WPF 上工作，其中有两个日期选择器，当我尝试检索有关日期范围的信息时，它在所有日期上仅显示一条记录(同一记录显示多次，例如:从 01/10/2013 - 3/中选择的日期) 10/2013)，我每天都有 3 条不同的记录，但我的输出是第一个记录显示 3 次，日期和时间相同。

function cpWhitelistStats() {
    $startDate = $_POST['startDate'];
    $startDateTime = "$startDate 00:00:00";
    $endDate = $_POST['endDate'];
    $endDateTime = "$endDate 23:59:59";
    $cpId = $_POST['id'];
    $cpName = etCommonCpNameById($cpId);

    print "<h2 style=\"text-align: center;\">Permitted Vehicle Summary</h2>";
    print "<h2 style=\"text-align: center;\">for $cpName</h2>";
    $tmpDate = explode("/", $startDate);
    $startYear = $tmpDate[2];
    $startMonth= $tmpDate[1];
    $startDay = $tmpDate[0];
    $tmpDate = explode("/", $endDate);
    $endYear = $tmpDate[2];
    $endMonth= $tmpDate[1];
    $endDay = $tmpDate[0];

    $startDateTime = "$startYear-$startMonth-$startDay 00:00:00";
    $endDateTime = "$endYear-$endMonth-$endDay 23:59:59";

    $custId = $_SESSION['customerID'];
    $realCustomerId = $_SESSION['realCustomerId'];

    $maxVal = 0;

    if ($custId != "") {
        $conn = &newEtConn($custId);
        // Get the whitelist plates
        $staticWhitelistArray = etCommonMkWhitelist($conn, $cpId);
        array_shift($staticWhitelistArray);

        $startLoopDate = strtotime($startDateTime);
        $endLoopDate = strtotime($endDateTime);
        $oneDay = 60 * 60 * 24;

        // Get the entries
        $plateList = array_keys($staticWhitelistArray);
        $plate_lookup = implode('","', $plateList);
        $sql = "SELECT plate, entry_datetime, exit_datetime FROM stats WHERE plate IN (\"$plate_lookup\") AND entry_datetime > \"$startDateTime\" AND entry_datetime < \"$endDateTime\" AND carpark_id=\"$cpId\" ";

您能否回显此查询，以便我们可以看到实际发送的内容...

$sql = "
SELECT plate
     , entry_datetime
     , exit_datetime 
  FROM stats 
 WHERE plate IN ('$plate_lookup') 
   AND entry_datetime BETWEEN '$startDateTime' AND '$endDateTime'
   AND carpark_id= '$cpId';
   ";

(这不是答案，但我想利用其他格式选项)
