update url wordpress

<?php
update_option( 'siteurl', 'http://example.com' );
update_option( 'home', 'http://example.com' );

change url wordpress

/*
This is the safer way to do it.
Upload this file to your active theme directory. 
Use your own URL instead of example.com, obviously.
Refresh in http://example.com/wp-login.php after adding/updating functions.php
Remove the lines or the remove the file after the site is up and running again.
