To change date format in PHP, the code is as follows−
Example
<?php
$date = "2019-11-11 05:25 PM";
echo "Displaying date...\n";
echo "Date = $date";
echo "\nDisplaying updated date...\n";
echo date('Y-m-d H:i', strtotime($date. ' + 20 days'));
?>Output
This will produce the following output−
Displaying date... Date = 2019-11-11 05:25 PM Displaying updated date... 2019-12-01 17:25
Example
Let us now see another example−
<?php
$date = date_create("2019-11-11");
echo "Displaying date...\n";
echo date_format($date,"Y/m/d H:i:s");
?>Output
This will produce the following output−
Displaying date... 2019/11/11 00:00:00
