Which PHP function can return the current date/time?
30 Answers
The time would go by your server time. An easy workaround for this is to manually set the timezone by using date_default_timezone_set
before the date()
or time()
functions are called to.
I'm in Melbourne, Australia so I have something like this:
date_default_timezone_set('Australia/Melbourne');
Or another example is LA - US:
date_default_timezone_set('America/Los_Angeles');
You can also see what timezone the server is currently in via:
date_default_timezone_get();
So something like:
$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;
So the short answer for your question would be:
// Change the line below to your timezone!
date_default_timezone_set('Australia/Melbourne');
$date = date('m/d/Y h:i:s a', time());
Then all the times would be to the timezone you just set :)
// Simply:
$date = date('Y-m-d H:i:s');
// Or:
$date = date('Y/m/d H:i:s');
// This would return the date in the following formats respectively:
$date = '2012-03-06 17:33:07';
// Or
$date = '2012/03/06 17:33:07';
/**
* This time is based on the default server time zone.
* If you want the date in a different time zone,
* say if you come from Nairobi, Kenya like I do, you can set
* the time zone to Nairobi as shown below.
*/
date_default_timezone_set('Africa/Nairobi');
// Then call the date functions
$date = date('Y-m-d H:i:s');
// Or
$date = date('Y/m/d H:i:s');
// date_default_timezone_set() function is however
// supported by PHP version 5.1.0 or above.
For a time-zone reference, see List of Supported Timezones.
Since PHP 5.2.0
you can use the DateTime()
class:
use \Datetime;
$now = new DateTime();
echo $now->format('Y-m-d H:i:s'); // MySQL datetime format
echo $now->getTimestamp(); // Unix Timestamp -- Since PHP 5.3
And to specify the timezone
:
$now = new DateTime(null, new DateTimeZone('America/New_York'));
$now->setTimezone(new DateTimeZone('Europe/London')); // Another way
echo $now->getTimezone();

This can be more reliable than simply adding or subtracting the number of seconds in a day or a month to a timestamp because of daylight saving time.
The PHP code
// 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)
PHP's time() returns a current Unix timestamp. With this, you can use the date() function to format it to your needs.
$date = date('Format String', time());
As Paolo mentioned in the comments, the second argument is redundant. The following snippet is equivalent to the one above:
$date = date('Format String');
You can either use the $_SERVER['REQUEST_TIME']
variable (available since PHP 5.1.0) or the time()
function to get the current Unix timestamp.
You can use both the $_SERVER['REQUEST_TIME']
variable or the time()
function. Both of these return a Unix timestamp.
Most of the time these two solutions will yield the exact same Unix Timestamp. The difference between these is that $_SERVER['REQUEST_TIME']
returns the time stamp of the most recent server request and time()
returns the current time. This may create minor differences in accuracy depending on your application, but for most cases both of these solutions should suffice.
Based on your example code above, you are going to want to format this information once you obtain the Unix Timestamp. Unformatted Unix time looks like: 1232659628
So in order to get something that will work, you can use the date()
function to format it.
A good reference for ways to use the date()
function is located in the PHP Manual.
As an example, the following code returns a date that looks like this: 01/22/2009 04:35:00 pm
:
echo date("m/d/Y h:i:s a", time());
PHP's date function can do this job.
Description:
string date(string $format [, int $timestamp = time()])
Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
Examples:
$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)
For the new PHP programmer might confuse why there are lot of method for to get current date and time and which one to use in their project.
1. date
method (PHP 4, PHP 5, PHP 7)
This is the very common and very easiest way to get the date and time in php.
// 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 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');
// Prints: July 1, 2000 is on a Saturday
echo "July 1, 2000 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2000));
/* 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: 2000-07-01T00:00:00+00:00
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));

2. DateTime
class (PHP 5 >= 5.2.0, PHP 7)
when you want to use PHP with OOP, this is the best way to get date and time.
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('@946684800');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "\n";
?>

3. Carbon Date time package
if you are using Composer, Laravel, Symfony or any kinda framework this is the best way to get the date and time. Also this package extends DateTime class in php so you use all the method in Datetime class. This in-built in frameworks like laravel so you don't have to install it separately.
printf("Right now is %s", Carbon::now()->toDateTimeString());
printf("Right now in Vancouver is %s", Carbon::now('America/Vancouver')); // automatically converted to string
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();
// Carbon embed 823 languages:
echo $tomorrow->locale('fr')->isoFormat('dddd, MMMM Do YYYY, h:mm');
echo $tomorrow->locale('ar')->isoFormat('dddd, MMMM Do YYYY, h:mm');
$officialDate = Carbon::now()->toRfc2822String();
$howOldAmI = Carbon::createFromDate(1975, 5, 21)->age;
$noonTodayLondonTime = Carbon::createFromTime(12, 0, 0, 'Europe/London');
$internetWillBlowUpOn = Carbon::create(2038, 01, 19, 3, 14, 7, 'GMT');
if (Carbon::now()->isWeekend()) {
echo 'Party!';
}
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

Hope this helps and if you know any other way to get the date and time feel free to edit the answer.
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('d-m-Y H:i:s');
Update
//Also get am/pm in datetime:
echo $date->format('d-m-Y H:i:s a'); // output 30-12-2013 10:16:15 am
For the date format, PHP date() Function is useful.
According to the article How to Get Current Datetime (NOW) with PHP, there are two common ways to get the current date. To get current datetime (now) with PHP, you can use the date
class with any PHP version, or better the datetime
class with PHP >= 5.2.
Various date format expressions are available here.
Example using date
This expression will return NOW in format Y-m-d H:i:s
.
<?php
echo date('Y-m-d H:i:s');
?>
Example using datetime class
This expression will return NOW in format Y-m-d H:i:s
.
<?php
$dt = new DateTime();
echo $dt->format('Y-m-d H:i:s');
?>
<?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)
?>
date(format, timestamp)
The date
function returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given. In other words, timestamp
is optional and defaults to the value of time().
And the parameters are -
format - Required. Specifies the format of the timestamp
timestamp - (Optional) Specifies a timestamp. Default is the current date and time
How to get a simple date
The required format parameter of the date()
function specifies how to format the date (or time)
.
Here are some characters that are commonly used for dates:
- d - Represents the day of the month (01 to 31)
- m - Represents a month (01 to 12)
- Y - Represents a year (in four digits)
- l (lowercase 'L') - Represents the day of the week
Other characters, like "/", ".", or "-"
can also be inserted between the characters to add additional formatting.
The example below formats today's date in three different ways:
<?php
echo "Today is " . date("Y/m/d") . "<br>";
echo "Today is " . date("Y.m.d") . "<br>";
echo "Today is " . date("Y-m-d") . "<br>";
echo "Today is " . date("l");
?>

- idate() - Format a local time/date as integer
- getdate() - Get date/time information
- getlastmod() - Gets time of last page modification
- mktime() - Get Unix timestamp for a date
- strftime() - Format a local time/date according to locale settings
- time() - Return current Unix timestamp

If you want a different timescale, please use:
$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");
Another simple way is to take the timestamp of the current date and time. Use mktime() function:
$now = mktime(); // Return timestamp of the current time
Then you can convert this to another date format:
//// Prints something like: Thursday 26th of January 2017 01:12:36 PM
echo date('l jS \of F Y h:i:s A',$now);
More date formats are here: http://php.net/manual/en/function.date.php
// 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));
If you are Bangladeshi, and if you want to get the time of Dhaka then use this:
$date = new DateTime();
$date->setTimeZone(new DateTimeZone("Asia/Dhaka"));
$get_datetime = $date->format('d.m.Y H:i:s');
Normally, this function for date is useful for everyone: date("Y/m/d");
But time is something different, because the time function depends on either the PHP version or system date.
So probably use it like this to get our own time zone:
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('H:m:s');
This function shows the 24 hours time.
$date = date('m/d/Y h:i:s a', time());
