我已经接受了along with another one of my post这个问题

如何获取php中的“日期编号”

2010-08-24 20:00:00.000

我想将当前日期编号分配给变量$ current_date_num，以便我可以在查询中使用它来比较数据库中已有的数据。

$query ="SELECT * FROM Reservations WHERE [Room_ID] = '$field' AND [Meeting Start] > '$current_date_num' ORDER BY [Meeting Start] asc ";

Answer 1

要获得上述格式的当前日期编号，您可以执行以下操作：

echo date("Y-m-d H:i:s.u")

Answer 2

如果您只在数据库中使用它，请考虑NOW

Answer 3

好吧，你可以得到这样的日期编号.. ex。来自php.net http://php.net/manual/en/function.date.php。

<?php
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone

    $today = date("F j, Y, g:i a");                 // March 10, 2001, 5:16 pm
    $today = date("m.d.y");                         // 03.10.01
    $today = date("j, n, Y");                       // 10, 3, 2001
    $today = date("Ymd");                           // 20010310
    $today = date('h-i-s, j-m-y, it is w Day');     // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
    $today = date('\i\t \i\s \t\h\e jS \d\a\y.');   // it is the 10th day.
    $today = date("D M j G:i:s T Y");               // Sat Mar 10 17:16:18 MST 2001
    $today = date('H:m:s \m \i\s\ \m\o\n\t\h');     // 17:03:18 m is month
    $today = date("H:i:s");                         // 17:16:18
    ?>

如果您尝试在用户侧的页面中指定它以这种方式使用
