Why is it necessary to have a link identifier as an input when using mysql_real_escape_string(). I know that the function should be used with MySQL queries, but the function is really just a string manipulation.

    From the PHP manual:

    Escapes special characters in the unescaped_string , taking into account the current character set of the connection so that it is safe to place it in a mysql_query(). If binary data is to be inserted, this function must be used.

    and:

    If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

    A connection is needed to determine the character set.
