How to Change The Site URL of a Wordpress installation
The Web Dev Zone is brought to you in partnership with Mendix. Discover how IT departments looking for ways to keep up with demand for business apps has caused a new breed of developers to surface - the Rapid Application Developer.
I also make sure that the db name, user and password are the same on development and production server. Here is what I use to make the installation work i.e. Wordpress ignors the site url saved in the db.
Add these lines in config.php to make the installation work on dev and on production
define('WP_HOME','http://' . $_SERVER['HTTP_HOST']); define('WP_SITEURL','http://' . $_SERVER['HTTP_HOST']);
