im trying to change the date format when im display the result [duplicate]

Answer 1

Follow the procedural style in php

<?php
$databaseDate = '2013-09-29 01:02:03';
$date = date_create($databaseDate);
echo date_format($date, 'd-m-y');
?>

You can also try strtotime()

<?php
$queryResultDate = mysqli_query("SELECT column_name FROM table_name"); //selecting the  date column
 $date = date("d-m-y" , strtotime($queryResultDate));
echo $date;
?>
