The documentation at: http://www.php.net/manual/en/function.mysql-real-escape-string.php
says: "mysql_real_escape_string() calls MySQL's library function mysql_real_escape_string"
.... and the documentation at: http://dev.mysql.com/doc/refman/5.0/en/mysql-real-escape-string.html
says: "must be a valid, open connection. This is needed because the escaping depends on the
character set in use by the server."
The php documentation also says: "If no such link is found, it will try to create one as if
mysql_connect() was called with no arguments."
RTFM... ;-)
