To convert the date-time format PHP provides strtotime() and date() function. We change the date format from one format to another.
Change YYYY-MM-DD to DD-MM-YYYY
<? php.
$currDate = "2020-04-18";
$changeDate = date("d-m-Y", strtotime($currDate));
echo "Changed date format is: ". $changeDate. " (MM-DD-YYYY)";
?>
<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');
?>
$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
// To change the format of an existing date
$old_date_format = "20/03/1999";
$new_data_format = date("Y-m-d H:i:s", strtotime($old_date_format));//Solution 1
$from = date('Y-m-d H:i a', strtotime($date_time));
echo $from;
//Solution 2
$date=date_create($date_time);
echo date_format($date,"Y/m/d H:i:s");<?php
$date = '05/05/2021';
echo DateTime::createFromFormat("d/m/Y", $date)->format('Y-m-d');
//2021-05-05
