哪个PHP函数可以返回当前日期/时间?


当前回答

获取当前时间和日期的最佳方法是使用PHP中的date函数:

$date = date('FORMAT'); // FORMAT E.g.: Y-m-d H:i:s

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

使用Unix时间戳:

$now_date = date('FORMAT', time()); // FORMAT Eg : Y-m-d H:i:s

设置服务器时区。

date_default_timezone_set('Asia/Calcutta');

这里有一个不同的时区列表。

由于使用夏令时,这比简单地在时间戳中添加或减去一天或一个月中的秒数更可靠。

PHP代码

// 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
$today = date("Y-m-d H:i:s");                   // 2001-03-10 17:16:18 (the MySQL DATETIME format)

日期格式也取决于:

echo date("d/m/Y H:i:sa"); // 13/04/2017 19:38:15pm

如果您想要不同的时间刻度,请使用:

$tomorrow  = mktime(0, 0, 0, date("m")  , date("d")+1, date("Y"));
$lastmonth = mktime(0, 0, 0, date("m")-1, date("d"),   date("Y"));
$nextyear  = mktime(0, 0, 0, date("m"),   date("d"),   date("Y")+1);

date_default_timezone_set("Asia/Calcutta");
echo date("Y/m/d H:i:s");
// Set the default timezone to use. Available since PHP 5.1
date_default_timezone_set('UTC');


// Prints something like: Monday
echo date("l");

// Prints something like: Monday 8th of August 2016 03:12:46 PM
echo date('l jS \of F Y h:i:s A');

// Prints: July 1, 2016 is on a Saturday
echo "July 1, 2016 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2016));

/* Use the constants in the format parameter */
// Prints something like: Wed, 25 Sep 2013 15:28:57 -0700
echo date(DATE_RFC2822);

// Prints something like: 2016-07-01T00:00:00+00:00
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));

如果你想获得日期,如12-3-2016,分开每一天,月和年的值,然后复制粘贴以下代码:

$day = date("d");
$month = date("m");
$year = date("y");
print "date" . $day . "-" . $month . "-" . $year;
