note 107101 deleted from function.mysql-real-escape-string by philip

Note Submitter: ovoznyak at gmail dot com ---- Function safe_string_escape($str) above is not properly working when $str is numeric (not string). For example, when call them as safe_string_escape((int) 12), it returns empty string. At the same time mysql_real_escape_string() returns 12. So, it is safe to add $str = (string) $str; in the begin of function.
