Set timezone in PHP and MySQL

by

In PHP:

<?php
define('TIMEZONE', 'Europe/Paris');
date_default_timezone_set(TIMEZONE);

For MySQL:

<?php
$now = new DateTime();
$mins = $now->getOffset() / 60;
$sgn = ($mins < 0 ? -1 : 1);
$mins = abs($mins);
$hrs = floor($mins / 60);
$mins -= $hrs * 60;
$offset = sprintf('%+d:%02d', $hrs*$sgn, $mins);

//Your DB Connection - sample
$db = new PDO('mysql:host=localhost;dbname=test', 'dbuser', 'dbpassword');
$db->exec("SET time_zone="$offset";");

The PHP and MySQL timezones are now synchronized within your application. No need to go for php.ini or MySQL console!
