Wordpress 4: WPLANG deprecated. How to change language programmatically?

Since WPLANG is deprecated in Wordpress 4, what do you use to set a user selected language? In versions 3.x.x I used define('WPLANG', $lang) to set a language and then on the pages could get it using get_locale(). I need to use this approach to differentiate the content for the different languages. I know that it's possible to change the language in Settings->General but I need to do that programmatically.

Thanks

Instead of juggling with global variables or constants one could use the filter locale to adapt the value on the fly. That would also be more fail-save for future releases.

add_filter( 'locale', function( $default_locale ) {
    if ( isset( $_SESSION[ 'WPLANG' ] ) )
        return $_SESSION[ 'WPLANG' ];

    return $default_locale;
} );

By the way, WPLANG as key in the session is likely at risk to cause a naming collision issue. Keep in mind that other WordPress plugins may also make usage of the global session.

I found a solution that works for me. Instead of using define ('WPLANG', $_SESSION['WPLANG']); I use $locale = $_SESSION['WPLANG']; .

With WordPress 4.0 the define WPLANG from wp-config.php is - as you have mentioned - depreciated. It has been replaced by an option called WPLANG stored in the table <TablePrefix>_options.

You could use get_option() to access it:

$my = get_option('WPLANG','en_US');

More details about the change can be found here.
