SQL :: 将 [INT] 显示为 [DD/MM/YYYY]

Question

我想以 DD/MM/YYYY 格式（或类似格式）显示 $eventdate（在 SQL Server 上保存为 unix 时间 INT 值）。

谢谢！

    ...
    $entry_display .= <<<ENTRY_DISPLAY
    <div class="post">
    $eventdate
    </div>
    ...

          WHERE eventdate > UNIX_TIMESTAMP()
          ORDER BY eventdate ASC
          LIMIT 30";
    $r = mysql_query($q);

    if ( $r !== false && mysql_num_rows($r) > 0 ) {
      while ( $a = mysql_fetch_assoc($r) ) {
        $title = stripslashes($a['title']);
        $author = stripslashes($a['author']);

Answer 1

只需将其通过 date() 函数即可。

$string = date("d/m/Y", $eventdate);

Answer 2

echo date("Y-m-d H:i:s", $eventdate);

就是你所需要的。

语法|：
字符串日期 ( string $format [, int $timestamp = time() ] )

Answer 3

您是否尝试过使用日期函数？看起来它正是满足您的需要。

Answer 4

如果我理解正确，您将使用 date() 函数。

$entry_display = date('m/d/Y', UNIX_TIMESTAMP_HERE);

您意识到 .= 是一种追加方式，对吧？如果没有更多代码，我不确定您的最终意图是什么，但这应该回答您吗？
