PHP notice in debug mode if HTTP_REFERER is not set

    Hi,
    I used WordPress 3.6.1 in debug mode, WP-Statistics 3.2 all running on PHP 5.4.19.

    When I browse, I strip my HTTP headers of the HTTP_REFERER header, and if WordPress is in debug mode, I get the following notice:

    Notice: Undefined index: HTTP_REFERER in wp-content/plugins/wp-statistics/includes/class/statistics.class.php on line 125

    I took a quick look at the code line in question and it seems that it assumes that $_SERVER['HTTP_REFERER'] will be set.

    Moreover, I’ve noticed that get_Referred() uses wpdb::escape() which is deprecated since WordPress 3.6.

    You’re right.
    But does it work

    For how long?
    It’s much easier to just use esc_sql(), pure function, no object. It would easier for me if the plugin ran clean in WP_DEBUG.

    I would also fix the other two, with this at Line 111:

    if( $default_referr ) {
	if( empty( $_SERVER['HTTP_REFERER'] ) ) {
		return esc_sql( get_bloginfo('url') );
	} else {
		return esc_sql(strip_tags($_SERVER['HTTP_REFERER']));
	}
} else {
	return esc_sql(strip_tags(@$_SERVER['HTTP_REFERER']));
}

    If return after else is you style ??
