Check if username doesn’t exists

Got it fixed. Pretty simple actually.

I moved the if part where the user get’s deleted to the bottom of the script.

foreach ($data as $gebruiker){
    $username = $gebruiker['username'];
    if ( username_exists( $username ) && $gebruiker['status'] == 'published' ){
        $user = get_user_by( 'login', $username);
        update_user_meta( $user->ID, 'import_1', $gebruiker['email'] );
    }else{
        $users = wp_insert_user(
        array( 
            'user_login'    =>  $gebruiker['username'],
            'user_pass'     =>  $gebruiker['password'],
            'first_name'    =>  $gebruiker['first_name'],
            'last_name'     =>  $gebruiker['last_name'],
            'user_email'    =>  $gebruiker['email'],
            'display_name'  =>  $gebruiker['first_name'] . ' ' . $gebruiker['last_name'],
            'nickname'      =>  $gebruiker['first_name'] . '' . $gebruiker['last_name'],
            'role'          =>  'subscriber'
             )                      
        );
        foreach ($data as $update_user) {
            update_user_meta( $users, 'import_1', $update_user['first_name'] );
            update_user_meta( $users, 'import_2', $update_user['last_name'] );
        }
    }if(username_exists( $username ) && $gebruiker['status'] == 'archived'){
        require_once(ABSPATH.'wp-admin/includes/user.php' );
        $user = get_user_by( 'login', $username);
        wp_delete_user( $user->ID );
    }
