不久

echo date('Y-m-d H:i:s');

php高级现在类额外的addMinute addYear，如addHour等…

使用

  echo now(); //2020-03-10 22:10


echo now()->addDay(1); //2020-03-11 22:10


echo now()->addDay(1)->addHour(1); // //2020-03-11 23:10


echo now()->addDay(1)->addHour(1)->addMinute(30); // //2020-03-11 23:40


echo now()->addDay(1)->addHour(1)->addMinute(30)->addSecond(10); // //2020-03-11 23:50

//or u can use get method for example

echo now()->addDay(1)->addHour(1)->addMinute(30)->get(); // //2020-03-11 23:40

没有内置的PHP now()函数，但可以使用date()来实现。

例子

function now() {
    return date('Y-m-d H:i:s');
}

如果需要更改时区，可以使用date_default_timezone_set()。

否则，您可以使用Carbon -一个简单的PHP API扩展DateTime。

或者你可以使用DateTime常量:

echo date(DateTime::W3C); // 2005-08-15T15:52:01+00:00

以下是他们的名单:

ATOM = "Y-m-d\TH:i:sP" ;               // -> 2005-08-15T15:52:01+00:00
COOKIE = "l, d-M-Y H:i:s T" ;          // -> Monday, 15-Aug-2005 15:52:01 UTC
ISO8601 = "Y-m-d\TH:i:sO" ;            // -> 2005-08-15T15:52:01+0000
RFC822 = "D, d M y H:i:s O" ;          // -> Mon, 15 Aug 05 15:52:01 +0000
RFC850 = "l, d-M-y H:i:s T" ;          // -> Monday, 15-Aug-05 15:52:01 UTC
RFC1036 = "D, d M y H:i:s O" ;         // -> Mon, 15 Aug 05 15:52:01 +0000
RFC1123 = "D, d M Y H:i:s O" ;         // -> Mon, 15 Aug 2005 15:52:01 +0000
RFC2822 = "D, d M Y H:i:s O" ;         // -> Mon, 15 Aug 2005 15:52:01 +0000
RFC3339 = "Y-m-d\TH:i:sP" ;            // -> 2005-08-15T15:52:01+00:00 ( == ATOM)
RFC3339_EXTENDED = "Y-m-d\TH:i:s.vP" ; // -> 2005-08-15T15:52:01.000+00:00
RSS = "D, d M Y H:i:s O" ;             // -> Mon, 15 Aug 2005 15:52:01 +0000
W3C = "Y-m-d\TH:i:sP" ;                // -> 2005-08-15T15:52:01+00:00

对于调试，我更喜欢一个更短的(3v4l.org):

echo date('ymd\THisP'); // 180614T120708+02:00

如果你现在想要包括上午/下午的时间

<?php 
    $time_now = date("Y-m-d h:i:s a");
    echo $time_now;
?>

输出时间2020-05-01 05:45:28 pm

or

<?php 
    $time_now = date("Y-m-d h:i:s A");
    echo $time_now;
?>

输出时间2020-05-01 05:45:28 PM

使用这个函数:

function getDatetimeNow() {
    $tz_object = new DateTimeZone('Brazil/East');
    //date_default_timezone_set('Brazil/East');

    $datetime = new DateTime();
    $datetime->setTimezone($tz_object);
    return $datetime->format('Y\-m\-d\ h:i:s');
}

MySQL函数NOW()返回当前时间戳。我发现PHP的唯一方法是使用下面的代码。

$curr_timestamp = date('Y-m-d H:i:s');
