With PHP version >= 5.4 DateTime can do this:-
echo (new \DateTime())->format('Y-m-d H:i:s');
Try this:
date("Y-m-d H:i:s");
shortly
echo date('Y-m-d H:i:s');

You can use the PHP date function with the correct format as the parameter,
echo date("Y-m-d H:i:s");

new \DateTime()
I like the solution posted by user1786647, and I've updated it a little to change the timezone to a function argument and add optional support for passing either a Unix time or datetime string to use for the returned datestamp.
It also includes a fallback for "setTimestamp" for users running version lower than PHP 5.3:
function DateStamp($strDateTime = null, $strTimeZone = "Europe/London") {
$objTimeZone = new DateTimeZone($strTimeZone);
$objDateTime = new DateTime();
$objDateTime->setTimezone($objTimeZone);
if (!empty($strDateTime)) {
$fltUnixTime = (is_string($strDateTime)) ? strtotime($strDateTime) : $strDateTime;
if (method_exists($objDateTime, "setTimestamp")) {
$objDateTime->setTimestamp($fltUnixTime);
}
else {
$arrDate = getdate($fltUnixTime);
$objDateTime->setDate($arrDate['year'], $arrDate['mon'], $arrDate['mday']);
$objDateTime->setTime($arrDate['hours'], $arrDate['minutes'], $arrDate['seconds']);
}
}
return $objDateTime->format("Y-m-d H:i:s");
}
Use this function:
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');
}
One more answer I find easy to use:
echo date('c');
// 2015-07-27T00:00:00+02:00
This is ISO 8601 date (added in PHP 5) which MySQL uses
MySQL 5.7 do not allow timezone in the datetime by default. You can disable the error with SQL_MODE=ALLOW_INVALID_DATES. See the answer here for more details: https://stackoverflow.com/a/35944059/2103434. But that also means that the timezone will be lost when saving to the database!
By default MySQL uses the system's timezone, and as long as PHP uses the same timezone you should be okay. In my case CET / UTC+2.
That means that if I insert 2015-07-27T00:00:00+02:00 to the database, only 2015-07-27T00:00:00 will be stored (but that is the correct local time!).
When I load the time back in to PHP,
$importedDate = new \DateTime('2015-07-27T00:00:00')
it will automatically assume it's +02:00 timezone since it's the default. Printing this will be correct again:
echo $importedDate->format('c');
// 2015-07-27T00:00:00+02:00
date_default_timezone_set('UTC');
$importedDate = new \DateTime('2015-07-27T00:00:00+02:00');
echo $importedDate->format('c');
// 2015-07-27T00:00:00+02:00
$importedDate->setTimezone(new \DateTimeZone("America/New_York"));
echo $importedDate->format('c');
// 2015-07-26T18:00:00-04:00
In PHP the logic equivalent of the MySQL's function now() is time().
But time() return a Unix timestamp that is different from a MySQL DATETIME.
So you must convert the Unix timestamp returned from time() in the MySQL format.
You do it with: date("Y-m-d H:i:s");
But where is time() in the date() function? It's the second parameter: infact you should provide to date() a timestamp as second parameter, but if it is omissed it is defaulted to time().
This is the most complete answer I can imagine.
Greetings.
date('Y-m-d H:i:s')
Look here for more details: http://pl.php.net/manual/en/function.date.php
I was looking for the same answer, and I have come up with this solution for PHP 5.3 or later:
$dtz = new DateTimeZone("Europe/Madrid"); //Your timezone
$now = new DateTime(date("Y-m-d"), $dtz);
echo $now->format("Y-m-d H:i:s");
Short answer
$now = date_create()->format('Y-m-d H:i:s');
Read below for the long answer.
The mimicry of the MySQL NOW() function in PHP
Here is a list of ways in PHP that mimic the MySQL NOW() function.
// relative date
$now = date_create('now')->format('Y-m-d H:i:s'); // works in php 5.2 and higher
$now = date_create()->format('Y-m-d H:i:s'); // also works in php 5.2
$now = new DateTime('now')->format('Y-m-d H:i:s'); // syntax error!!!
$now = (new DateTime('now'))->format('Y-m-d H:i:s'); // works in php 5.4 and higher
$now = date('Y-m-d H:i:s'); // Slightly higher performance, but less usable for date/time manipulations
// From Unix timestamp
// Using date_create() with a Unix timestamp will give you a FALSE,
// and if you try to invoke format() on a FALSE then you'll get a:
// Fatal error: Call to a member function format() on boolean
// So if you work with Unix timestamps then you could use: date_create_from_format().
$unixTimeStamp = 1420070400; // 01/01/2015 00:00:00
$y2015 = date_create_from_format('U', $unixTimeStamp, timezone_open('Europe/Amsterdam'))->format('Y-m-d H:i:s');
$y2015 = date('Y-m-d H:i:s', $unixTimeStamp);
I think that date_create()->format('Y-m-d H:i:s') is the best way because this approach allows you to handle time/time-zone manipulations easier than date('Y-m-d H:i:s') and it works since php 5.2.
The MySQL function NOW() gives the dateTime value in this format: 'YYYY-MM-DD HH:MM:SS'. See here: https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_now.
An interesting fact is that it's possible to get the datetime format by running this query: SHOW VARIABLES LIKE 'd%e_format', the result could be something like this:
Variable_name Value
date_format %Y-%m-%d
datetime_format %Y-%m-%d %H:%i:%s
The variables up here are read-only variables. So you can't change it.
I guess the MySQL NOW() function gets it's format from the datetime_format variable.
The advantages of date_create()->format() instead date() summary
The favorable facts of date_create('now')->format('Y-m-d H:i:s') over date('Y-m-d H:i:s') are:
The disadvantages of date_create()->format() instead date()
The function date() has a slightly better performance than date_create()->format(). See benchmark test below.
$start = time();
for ($i = 0; $i <= 5000000; $i++) {
$a = date_create('now')->format('Y-m-d H:i:s');
}
$end = time();
$elapsedTimeA = $end - $start;
echo 'Case A, elapsed time in seconds: ' . $elapsedTimeA;
echo '<br>';
$start = time();
for ($i = 0; $i <= 5000000; $i++) {
$b = date('Y-m-d H:i:s');
}
$end = time();
$elapsedTimeB = $end - $start;
echo 'Case B, elapsed time in seconds: ' . $elapsedTimeB;
echo '<br>';
// OUTPUT
Case A, elapsed time in seconds: 31
Case B, elapsed time in seconds: 14
The upper case shows that date() is faster. However, if we change the test scenario a bit, then outcome will be different. See below:
$start = time();
$dt = date_create('now');
for ($i = 0; $i <= 5000000; $i++) {
$a = $dt->format('Y-m-d H:i:s');
}
$end = time();
$elapsedTimeA = $end - $start;
echo 'Case A, elapsed time in seconds: ' . $elapsedTimeA;
echo '<br>';
$start = time();
for ($i = 0; $i <= 5000000; $i++) {
$b = date('Y-m-d H:i:s');
}
$end = time();
$elapsedTimeB = $end - $start;
echo 'Case B, elapsed time in seconds: ' . $elapsedTimeB;
echo '<br>';
// OUTPUT
Case A, elapsed time in seconds: 14
Case B, elapsed time in seconds: 15
The DateTime method: format() is faster here than date().
The advantages of date_create()->format() instead date() detailed
Read on for the detailed explanation.
easier to handle time manipulations
date_create() accepts a relative date/time format (like now, yesterday or +1 day) see this link, example:
$tomorrow = date_create('+1 day')->format('Y-m-d H:i:s');
date() accepts a relative date/time format as well, like this:
$tomorrow = date('Y-m-d H:i:s', strtotime('+1 day'));
$tomorrow = date('Y-m-d H:i:s', (time() + 86400)); // 86400 seconds = 1 day
easier to handle timezones
When timezones matter then the usage of date_create()->format() makes a lot more sense then date() because date() uses the default time zone which is configured in php.ini at the date.timezone directive. Link: http://php.net/manual/en/datetime.configuration.php#ini.date.timezone .
It is possible to change the timezone during run-time. Example:
date_default_timezone_set('Asia/Tokyo');.
The downside of that is that it will affect all date/time functions. This problem doesn't exists if you are using date_create()->format() in combination with timezone_open().
PHP supports major timezones. The funny thing is that it even supports the Arctic circle, and Antarctica. Have you ever heard about Longyearbyen? If not, then don't worry, neither did I until I read the official PHP documentation.
$nowLongyearbyen = date_create('now', timezone_open('Arctic/Longyearbyen'))->format('Y-m-d H:i:s');
See a list of all supported timezones: http://php.net/manual/en/timezones.php.
o.o.p.
O.O.P. uses state-full Objects. So I prefer to think in this way:
// Create a DateTime Object.
// Use the DateTime that applies for tomorrow.
// Give me the datetime in format 'Y-m-d H:i:s'
$tomorrow = date_create('+1 day')->format('Y-m-d H:i:s');
Then to think in this way:
// Give me a date time string in format 'Y-m-d H:i:s',
// use strtotime() to calculate the Unix timestamp that applies for tomorrow.
$tomorrow = date('Y-m-d H:i:s', strtotime('+1 day'));
Therefore I would say that the date_create()->format() approach is more readable to me then date().
date_create() VS new DateTime()
The favorable facts of date_create() over new DateTime() are:
Namespaces
If you work in a namespace and want to initialise a DateTime object with the new keyword, then you have to do it like this:
namespace my_namespace;
// The backslash must be used if you are in a namespace.
// Forgetting about the backslash results in a fatal error.
$dt = new \DateTime();
There is nothing wrong with this, but the downside of the above is that people forget sporadically about the backslash. By using the date_create() constructor function you don't have to worry about namespaces.
$dt = date_create(); // in or not in a namespace it works in both situations
Example of date_create()->format()
I use this approach for my projects if I have to fill an array. Like this:
$array = array(
'name' => 'John',
'date_time' => date_create('now')->format('Y-m-d H:i:s'), // uses the default timezone
'date_time_japan' => date_create('now', timezone_open('Asia/Tokyo'))->format('Y-m-d H:i:s'),
);
The PHP equivalent is time(): http://php.net/manual/en/function.time.php
There is no built-in PHP now() function, but you can do it using date().
Example
function now() {
return date('Y-m-d H:i:s');
}
You can use date_default_timezone_set() if you need to change timezone.
Otherwise you can make use of Carbon - A simple PHP API extension for DateTime.
If you want to get time now including AM / PM
<?php
$time_now = date("Y-m-d h:i:s a");
echo $time_now;
?>
It outputs 2020-05-01 05:45:28 pm
or
<?php
$time_now = date("Y-m-d h:i:s A");
echo $time_now;
?>
It outputs 2020-05-01 05:45:28 PM
Or you can use DateTime constants:
echo date(DateTime::W3C); // 2005-08-15T15:52:01+00:00
Here's the list of them:
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
For debugging I prefer a shorter one though (3v4l.org):
echo date('ymd\THisP'); // 180614T120708+02:00
MySQL function NOW() returns the current timestamp. The only way I found for PHP is using the following code.
$curr_timestamp = date('Y-m-d H:i:s');
My answer is superfluous, but if you are OCD, visually oriented and you just have to see that now keyword in your code, use:
date( 'Y-m-d H:i:s', strtotime( 'now' ) );
