Simple email function for PHP

Simple function to send an email in PHP, and that actually works 😉

Just be aware that I added a Hook (check the PHP Hook class).

/**
     * Simple function to send an email
     *
     * @param string $to
     * @param string $from
     * @param string $subject
     * @param string $body
     * @param string $extra_header
     * @return boolean
     */
    function email($to,$from,$subject,$body,$headers=NULL)
    {
        //we add hook just in case we want to overwrite the email function
        //example    Hook::add_action('email','some_function_used_instead_email');
        if (Hook::exists_action('email'))
        {
            return Hook::do_action('email',func_get_args());
        }
        else
        {
            if ($headers==NULL)
            {
                $headers = 'MIME-Version: 1.0' . PHP_EOL;
                $headers.= 'Content-type: text/html; charset=utf8'. PHP_EOL;
                $headers.= 'From: '.$from.PHP_EOL;
                $headers.= 'Reply-To: '.$from.PHP_EOL;
                $headers.= 'Return-Path: '.$from.PHP_EOL;
                $headers.= 'X-Mailer: PHP/' . phpversion().PHP_EOL;
            }

            return mail($to,$subject,$body,$headers);
        }
    }
