Using a datetime field from a mysql database e.g. "2012-03-24 17:45:12"


= mysql_query("SELECT `datetime` FROM `table`");
$row = mysql_fetch_row($result);
$date = date_create($row[0]);

date_format($date, 'Y-m-d H:i:s');
#output: 2012-03-24 17:45:12

echo date_format($date, 'd/m/Y H:i:s');
#output: 24/03/2012 17:45:12

echo date_format($date, 'd/m/y');
#output: 24/03/12

echo date_format($date, 'g:i A');
#output: 5:45 PM

echo date_format($date, 'G:ia');
#output: 05:45pm

echo date_format($date, 'g:ia \o\n l jS F Y');
#output: 5:45pm on Saturday 24th March 2012

For full reference of the supported format character and results,

Seems like datetime::format does not really support microseconds as the documentation under date suggest it will.

Here is some code to generate a datetime with microseconds and timezone:

private function udate($format = 'u', $utimestamp = null) {
        if (is_null($utimestamp))
            $utimestamp = microtime(true);

        $timestamp = floor($utimestamp);
        $milliseconds = round(($utimestamp - $timestamp) * 1000000);

        return date(preg_replace('`(?<!\\\\)u`', $milliseconds, $format), $timestamp);

echo udate('Y-m-d H:i:s.u T');
// Will output something like: 2014-01-01 12:20:24.42342 CET

$saved_time="2019-03-09 14:25:20";
    $formated_saved_time = new DateTime($saved_time);
    $current_time = new DateTime();
    $interval = $current_time->diff($formated_saved_time);
      if (!empty($interval->format('%a'))){
       $time_difference=$interval->format('%a days ago');
        } elseif ($formated_saved_time->format('d') != $current_time->format('d')){
             }elseif (!empty($interval->format('%h'))){
                     $time_difference=$interval->format('%h hr, %i min ago');
                     } elseif (!empty($interval->format('%i'))){
                              $time_difference=$interval->format('%i min ago');
                              } elseif (!empty($interval->format('%s'))){
                                $time_difference=$interval->format('%s sec ago');

There is a bit confusing logic may appear using year week number:

echo (new \DateTime("2018-12-31 13:05:21"))->format("YW") . PHP_EOL;

will output 201801, not 201901 nor 201852, because of strange ISO_8601-2004 standard: the  first  calendar  week  of  a  year  is  that  one  which  includes  the  first  Thursday  of  that  year, so this date (it is Monday) do belong to the first week of 2019 (this is why 'W' format gives 01), but internal timestamp is of 2018 (and 'Y' format obey this), therefore getting us unexpected result of 201801. So be careful when using this output with something important (i know projects where this was used to form MySQL partitions).

The date_format can be use to get the last day of February:


function last_day_of_feb ($year) {
# The 0th day of a month is the same as the last day of the month before
$ultimo_feb_str = $year . "-03-00";
$ultimo_feb_date = date_create($ultimo_feb_str);
$return = date_format($ultimo_feb_date, "Y-m-d");

last_day_of_feb(2011) . "\n"; # 2011-02-28
echo last_day_of_feb(2012) . "\n"; # 2011-02-29

The udate function is a great start, but the formatting of the milliseconds is a little off. If it is within the first 100000 microseconds then the string will be less than 6 characters, so 0.012435 will appear as 0.12345. The revision below fixes this.

function udate($strFormat = 'u', $uTimeStamp = null)

    // If the time wasn't provided then fill it in
    if (is_null($uTimeStamp))
        $uTimeStamp = microtime(true);

    // Round the time down to the second
    $dtTimeStamp = floor($uTimeStamp);

    // Determine the millisecond value
    $intMilliseconds = round(($uTimeStamp - $dtTimeStamp) * 1000000);
    // Format the milliseconds as a 6 character string
    $strMilliseconds = str_pad($intMilliseconds, 6, '0', STR_PAD_LEFT);

    // Replace the milliseconds in the date format string
    // Then use the date function to process the rest of the string
    return date(preg_replace('`(?<!\\\\)u`', $strMilliseconds, $strFormat), $dtTimeStamp);

I believe this is a bug but its note-worthy if it is intended (I am using PHP 5.5.3).

$ php --version

What is happening:

DateTime()->format() will modify the timezone. So do not expect the public date property to be returned (format mask applied) based on the current public timezone property. format will decide that when calling ->format() it will use the server timezone which eliminates all usefulness of ->setTimezone().

= new \DateTime( 'now',  new \DateTimeZone( 'UTC' ) );
$nowUtc = new \DateTime( 'now',  new \DateTimeZone( 'UTC' ) );
'$nowUtc->format(\'Y-m-d h:i:s\')'.PHP_EOL;
var_dump($nowUtc->format('Y-m-d h:i:s'));
$nowUtc->setTimezone( new \DateTimeZone( 'Australia/Sydney' ) );
'$nowUtc->setTimezone( new \DateTimeZone( \'Australia/Sydney\' ) )'.PHP_EOL;
'$nowUtc->format(\'Y-m-d h:i:s\')'.PHP_EOL;
var_dump($nowUtc->format('Y-m-d h:i:s'));exit;



  public 'date' => string '2014-02-13 02:42:48' (length=19)
  public 'timezone_type' => int 3
  public 'timezone' => string 'UTC' (length=3)

$nowUtc->format('Y-m-d h:i:s')

string '2014-02-13 02:42:48' (length=19)

$nowUtc->setTimezone( new \DateTimeZone( 'Australia/Sydney' ) )

  public 'date' => string '2014-02-13 13:42:48' (length=19)
  public 'timezone_type' => int 3
  public 'timezone' => string 'Australia/Sydney' (length=16)

$nowUtc->format('Y-m-d h:i:s')

string '2014-02-13 01:42:48' (length=19) // expected 2014-02-13 13:42:48 based on Australia/Sydney - what is 2014-02-13 01:42:48 from anyway!
