Wordpress auto login from custom page

In my wordpress website I have created a custom registration page to register in Wordpress using "PHP Code" plugin. Now I wanted to auto login the users when they complete the registration. I did lot of research but couldn't find a solution for my problem. I tried the following sample snippet to test in the custom page :

<?php

//Log in a WordPress user programmatically
function auto_login( $user ) {
    $username   = $user;
    if ( !is_user_logged_in() ) {
        $user = get_user_by('login', $username );
        $user_id = $user->ID;
        wp_set_current_user( $user_id, $user_login );
        wp_set_auth_cookie( $user_id );
        do_action( 'wp_login', $user_login );
    }     
}

auto_login('admin');

?>

But I am getting following errors.

Warning: Cannot modify header information - headers already sent by (output started at /home/content/19/11054119/html/wp-content/plugins/sitepress-multilingual-cms/inc/language-switcher.php:921) in /home/content/19/11054119/html/wp-includes/pluggable.php on line 925

So I am wondering is there anyway to do auto login without touching the theme functions. If you have any idea or solution help me with this..

Thanks

You should use the core function wp_signon https://codex.wordpress.org/Function_Reference/wp_signon this is the sample code

function custom_login() {
    $creds = array();
    $creds['user_login'] = 'example';
    $creds['user_password'] = 'plaintextpw';
    $creds['remember'] = true;
    $user = wp_signon( $creds, false );
    if ( is_wp_error($user) )
        echo $user->get_error_message();
}

You can try this way:

   if( isset($_POST['log']) && isset($_POST['pwd']) ):
      $creds = array( 'user_login' =>  $_POST['log'], 'user_password' => $_POST['pwd'], 'remember' => $_POST['rememberme'] );
      $user = wp_signon( $creds, false );
      if ( is_wp_error($user) ): echo $user->get_error_message(); endif;
      wp_set_current_user($user->ID);
      return $user;
    endif;

 //Log in a WordPress user programmatically
        function auto_login( $username ) {            
            if ( !is_user_logged_in() ) {
                $UserData = get_user_by('login', $username );
                $iUserid = $UserData->ID;
                $UserLogin = $UserData->user_login;
                wp_set_current_user($iUserid, $UserLogin);
                wp_set_auth_cookie($iUserid);
                do_action('wp_login', $UserLogin);
            }     
        }

        auto_login('admin');
