我这里有一个简单的脚本,只是为了从2日期范围中提取mysql的记录。奇怪的是它只显示4条记录,而有6条记录,我没有对记录设置任何限制。任何人都可以帮助我吗?

尝试选择: - 2月1日至2月27日

这是我的代码: -

$done = 0;
function displayTable($results) {
    $total_result = count($results);
    echo $total_result." results found.";
    for($x = 1; $x <= $total_result; $x++) {
        //echo "<tr><td>$allresult['id'][$x]</td>";
        echo "<tr><td>".$results['date'][$x]."</td>";
        echo "<td>".$results['url'][$x]."</td>";
        echo "<td>".$results['clickid'][$x]."</td>";
        echo "<td>".$results['code'][$x]."</td></tr>";
    }
}

if (isset($_POST['sub'])) {

$datefrom = $_POST['fromdatetime'];
$dateto = $_POST['todatetime'];

if ($datefrom == "From" || $datefrom == "" && $dateto == "To" || $dateto == "") {
    echo "ERROR! No date/time selected";
}
else {
    /* create a prepared statement */
    $stmt = mysqli_prepare($mysqli, "SELECT * FROM data WHERE date_data between (?) AND (?)");

    /* bind parameters for markers */
    mysqli_stmt_bind_param($stmt, "ss", $datefrom, $dateto);

    /* execute query */
    mysqli_stmt_execute($stmt);

    /* bind result variables */
    mysqli_stmt_bind_result($stmt, $resultid, $resulturl, $resultdate, $resultclickid, $resultcode);

    $resultcount = 0;
    $allresult = array();

    /* fetch value */
    while (mysqli_stmt_fetch($stmt)) {
       //$allresult['id'][$resultcount] =  $resultid;
       $allresult['url'][$resultcount] =  $resulturl;
       $allresult['date'][$resultcount] =  $resultdate;
       $allresult['clickid'][$resultcount] =  $resultclickid;
       $allresult['code'][$resultcount] =  $resultcode;
       $resultcount++;
    }

    /* close statement */
    mysqli_stmt_close($stmt);


/* close connection */
mysqli_close($mysqli);
$done = 1;
}
}
?>

问题是你在计算第一个数组。您目前有一个多维数组,而您只计算第一个数组有多少个数组。

因为您在此处将4个不同的值存储到数组中

$allresult['url'][$resultcount] =  $resulturl;
$allresult['date'][$resultcount] =  $resultdate;
$allresult['clickid'][$resultcount] =  $resultclickid;
$allresult['code'][$resultcount] =  $resultcode;

当您执行count($allresult)时,它会输出4,因为$allresult包含4个子数组,urldateclickid和{{ 1}}。

然后使用code循环在for函数中输出数组。首先,你从1开始计数(而数组以索引0开始),但更重要的是,这里的计数只有4,因为第一层数组包含4个子数组(如上所述)。

我会使用displayTable - 循环重写函数,因为它更适合循环遍历数组。但是,您可以更改以便foreach函数通过其中一个子数组进行计数,方法是更改​​函数

count

function displayTable($results) {
    $total_result = count($results); // Outputs static 4, generated in the while-loop
    echo $total_result." results found.";

    for($x = 1; $x <= $total_result; $x++) {
        // continue here...

这里实质上改变的是function displayTable($results) { $total_result = count($results['url']); // Actual counts of instances found from the query echo $total_result." results found."; for($x = 0; $x < $total_result; $x++) { // continue here... x = 1; $x <= $total_result,最重要的是,从$x = 0; $x < $total_result$total_result = count($results);

更新您的查询

SELECT * FROM data WHERE date_data between (?) AND (?)

SELECT * FROM data WHERE DATE(date_data) between (?) AND (?)

它可能会奏效。 假设您的第一个参数日期低于第二个参数日期
