你可以:

$now = strtotime(date('Y-m-d H:i:s')); // = Now 

完整的格式选项请参见文档:https://www.php.net/manual/en/function.date.php

非常简单 echo $date = date('Y-m-d H:i:s');

Linux服务器时间与PHP time()时区差异如下:

<?php
    putenv("TZ=Asia/Kabul");
    $t = time();
    echo date('d/m/Y H:i:sa', $t);
?>

您可以简单地使用这段代码来获取当前日期和时间

echo date('r', time());

<?php
echo "<b>".date('l\, F jS\, Y ')."</b>";
?>
