int mysql_get_proto_info ( [resource link_identifier] )
Retrieves the MySQL protocol.
Parameters
link_identifier
The MySQL connection. 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 by chance no connection is found or established, an
E_WARNING level warning is generated.
Return Values
Returns the MySQL protocol on success, or FALSE on failure.
