我想在每个星期三上午12点更新我的日期。在PHP的下拉列表中

Question

我想在每个星期三上午12点更新我的日期。在PHP的下拉列表中保持不变直到下周三。

以下是我的代码：

$now    = time(); // current timestamp
$today  = date("w", $now); // "w" returns the weekday (number)
$wednesday = 3; // 5th day of the week (sunday = 0)

if ($today == $wednesday) {
    $ts       = $now; // today is wednesday, don't change the timestamp
    $daysLeft = 0; // no days left!
} else {

    $daysLeft = $wednesday-$today; // get the left days
    $ts = $now + 84600 * $daysLeft; // now + seconds of one day * days left
}

?>

<h1>
    Forecast for <?php echo date("Y-m-d", $ts) ?>
</h1>

它在星期三的日期保持不变，这是正确的，然后在星期四开始后迅速改变。虽然我希望它能在下周三之前保持不变。

Answer 1

我认为你的问题太复杂了。

<?php
$today = time();
$nextWed = strtotime('next wednesday');

if(date('D', $today) === 'Wed') {
    $ts = date('Y-m-d', $today);
} else {
    $ts = date('Y-m-d', $nextWed);
}
echo '<h1>Forecast for '.$ts.'</h1>';
?>

发生了什么？

1. 获取今天的时间戳
2. 获取下周三的时间戳
3. 如果今天是星期三，$ts =今天的日期
4. 如果今天不是星期三，$ts =下周三的日期
5. 回应您的结果

快乐的编码！

修改

<?php
$now = time();
$today = date('Y-m-d', $now);
if(date('D', $now) === 'Wed') { $nextWed = strtotime($today); }
if(date('D', $now) === 'Thu') { $nextWed = strtotime("$today - 1 days"); }
if(date('D', $now) === 'Fri') { $nextWed = strtotime("$today - 2 days"); }
if(date('D', $now) === 'Sat') { $nextWed = strtotime("$today - 3 days"); }
if(date('D', $now) === 'Sun') { $nextWed = strtotime("$today - 4 days"); }
if(date('D', $now) === 'Mon') { $nextWed = strtotime("$today - 5 days"); }
if(date('D', $now) === 'Tue') { $nextWed = strtotime("$today - 6 days"); }
$ts = date('Y-m-d', $nextWed);
echo '<h1>Forecast for '.$ts.'</h1>'
?>
