我正在处理以下代码（使用 php 和 javascript 的倒数计时器）。我想要做的是($end_date)从 mysql 获取日期时间并将其$date =''放在我的代码中。

如果我在这样的代码中手动输入日期和时间，这段代码就可以正常工作：$date = 'September 17 2013 12:00:00 PM GMT';

但我需要它像这样工作：

$date = echo $dynamicList;

或者像这样：

$date = echo $end_date;

我不确定我做错了什么！

这是我的完整代码：

<?php 
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php date_default_timezone_set('GMT'); ?>
<?php
session_start();
// Run a select query to get my letest 6 items
// Connect to the MySQL database  
include "config/connect.php";
$dynamicList = "";
$sql = "SELECT * FROM item ORDER BY id";
$query = mysqli_query($db_conx, $sql);
$productCount = mysqli_num_rows($query); // count the output amount
if ($productCount > 0) {
    while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $product_name = $row["product_name"];
             $date_added = strftime("Y-m-d", strtotime($row["date_added"]));
             $end_date = strftime("Y-m-d H:i:s", strtotime($row["end_date"]));
             $price = $row["price"];
             $dynamicList .= '<div>' . $end_date . '
      </div>';
    }
} else {
    $dynamicList = "No Records";
}
?>

<?php
$date = echo $dynamicList;
$exp_date = strtotime($date);
$now = time();

if ($now < $exp_date) {
?>
<script>
// Count down milliseconds = server_end - server_now = client_end - client_now
var server_end = <?php echo $exp_date; ?> * 1000;
var server_now = <?php echo time(); ?> * 1000;
var client_now = new Date().getTime();
var end = server_end - server_now + client_now; // this is the real end time

var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24
var timer;

function showRemaining()
{
    var now = new Date();
    var distance = end - now;
    if (distance < 0 ) {
       clearInterval( timer );
       document.getElementById('countdown').innerHTML = 'EXPIRED!';

       return;
    }
    var days = Math.floor(distance / _day);
    var hours = Math.floor( (distance % _day ) / _hour );
    var minutes = Math.floor( (distance % _hour) / _minute );
    var seconds = Math.floor( (distance % _minute) / _second );

    var countdown = document.getElementById('countdown');
    countdown.innerHTML = '';
    if (days) {
        countdown.innerHTML += 'Days: ' + days + '<br />';
    }
    countdown.innerHTML += 'Hours: ' + hours+ '<br />';
    countdown.innerHTML += 'Minutes: ' + minutes+ '<br />';
    countdown.innerHTML += 'Seconds: ' + seconds+ '<br />';
}

timer = setInterval(showRemaining, 1000);
</script>
<?php
} else {
    echo "Times Up";
}
?>
<div id="countdown"></div>

有人可以帮我解决这个问题吗？

我的页面上没有任何错误。只有一个空白页，如果我更改 $date = echo $dynamicList;为，$date = '$dynamicList';我会收到 Times Up 消息！

任何帮助，将不胜感激。

编辑我的新代码：

<?php 
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php date_default_timezone_set('GMT'); ?>
<?php
session_start();
// Run a select query to get my letest 6 items
// Connect to the MySQL database  
include "config/connect.php";
$dynamicList = "";
$sql = "SELECT * FROM item ORDER BY id";
$query = mysqli_query($db_conx, $sql);
$productCount = mysqli_num_rows($query); // count the output amount
if ($productCount > 0) {
    while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){ 
             $id = $row["id"];
             $product_name = $row["product_name"];
             $date_added = strftime("%Y-%m-%d", strtotime($row["date_added"]));
             $end_date = strftime("%Y-%m-%d %H:%M:%S", strtotime($row["end_date"]));
             $price = $row["price"];
             $dynamicList .= '<div>' . $end_date . '
      </div>';
    }
} else {
    $dynamicList = "No Records";
}
?>

<?php
$date = "'".$end_date."'";
$exp_date = strtotime($date);
$now = time();

if ($now < $exp_date) {
?>
<script>
// Count down milliseconds = server_end - server_now = client_end - client_now
var server_end = <?php echo $exp_date; ?> * 1000;
var server_now = <?php echo time(); ?> * 1000;
var client_now = new Date().getTime();
var end = server_end - server_now + client_now; // this is the real end time

var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24
var timer;

function showRemaining()
{
    var now = new Date();
    var distance = end - now;
    if (distance < 0 ) {
       clearInterval( timer );
       document.getElementById('countdown').innerHTML = 'EXPIRED!';

       return;
    }
    var days = Math.floor(distance / _day);
    var hours = Math.floor( (distance % _day ) / _hour );
    var minutes = Math.floor( (distance % _hour) / _minute );
    var seconds = Math.floor( (distance % _minute) / _second );

    var countdown = document.getElementById('countdown');
    countdown.innerHTML = '';
    if (days) {
        countdown.innerHTML += 'Days: ' + days + '<br />';
    }
    countdown.innerHTML += 'Hours: ' + hours+ '<br />';
    countdown.innerHTML += 'Minutes: ' + minutes+ '<br />';
    countdown.innerHTML += 'Seconds: ' + seconds+ '<br />';
}

timer = setInterval(showRemaining, 1000);
</script>
<?php
} else {
    echo "Times Up";
}
?>
<div id="countdown"></div>

更改这些行：

$date = echo $dynamicList;

使用以下代码：

$date = "'".$end_date."'";

并将 定义$end_date为全局变量。

并在下面为时区添加更多参数：

$end_date = strftime("Y-m-d H:i:s A T", strtotime($row["end_date"]));
                                 ^^^ add these

由于您的 if 条件不正确，您收到了超时消息：

if ($now < $exp_date) {

当您将 unixtimestap 与时间格式进行比较时。

使用此代码：

$date = "'".$end_date."'";
$exp_date = strtotime($date);
$now = strtotime(date("Y-m-d H:i:s A T"));

然后比较这些时间。您还需要更改 $now 。
