我发现在PHP中获取当前时间的最简单方法是这样的。

//Prints out something like 10:00am Just be sure to set your timezone correctly.
date_default_timezone_set("America/Chicago");
$TIME = date('G:ia'); 

<?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
$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

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

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

像这样的指纹

2012年12月9日，星期天

下面是一些常用的表示时间的字符:

d -表示一个月中的第一天(01 ~ 31) m -代表一个月(01 ~ 12) Y -年份(四位数) l(小写“l”)-代表星期几 H -以小时为单位的24小时格式(00至23) H -以前导零表示的12小时格式(01到12) i -前导0的分钟(00到59) s -前导0的秒(00到59) a -小写的子午线前后(am或pm)

例子:

echo "Today " . date("Y/m/d") ;
echo "time " . date("h:i:sa");
