 I have a local Multisite installation with the following domain:

 www.wordpress.dev

 I create a new site called: demo1.wordpress.dev, which is fine and works
 as expected (the www. is trimmed as expected too).

 When I try the following code:

 {{{ $result = get_id_from_blogname( 'demo1' ); }}}

 $result is false and not the Blog ID.

 I think that the issue is located inside the get_id_from_blogname
 function:

 {{{ $domain = $slug . '.' . $current_site->domain; }}}
 should be
 {{{ $domain = $slug . '.' . preg_replace( '|^www\.|', '',
 $current_site->domain ); }}}

 But I'm not sure if this could affect other areas.
