class proxy extends MysqlndUhConnection {
public function setServerOption ( $res , $option ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
printf ( "Option '%s' set\n" , server_option_to_string ( $option ));
$ret = parent :: setServerOption ( $res , $option );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
$mysqli -> multi_query ( "SELECT 1; SELECT 2" );
