#17894: WP_User class uses ID as username when $id = null
--------------------------+-----------------------------

 Priority:  normal        |  Milestone:  Awaiting Review
Component:  General       |    Version:  3.1.3
 Severity:  normal        |   Keywords:  has-patch

 WP_User's `__construct()` function has:

 {{{
 if ( ! is_numeric( $id ) ) {
         $name = $id;
         $id = 0;
 }
 }}}

 presumably for when people incorrectly pass the username as the ID.
 However, this also returns true when the ID is set as null and is used as
 the username.

 '''Code to reproduce:'''

 {{{
 add_action( 'admin_init', 'display_admin_user' );

 function display_admin_user() {
         $user_by_name = new WP_User( null, 'admin' );
         $user_by_id = new WP_User( 1 );

         echo '<p>' . print_r( $user_by_name, true ) . '</p>';
         echo '<p>' . print_r( $user_by_id, true ) . '</p>';
 }
 }}}
