Example #1 MysqlndUhConnection::changeUser() example
<?phpclass proxy extends MysqlndUhConnection { /* Hook mysqlnd's connection::change_user call */ public function changeUser($res, $user, $passwd, $db, $silent, $passwd_len) { printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true)); $ret = parent::changeUser($res, $user, $passwd, $db, $silent, $passwd_len); printf("%s returns %s\n", __METHOD__, var_export($ret, true)); return $ret; }}/* Install proxy/hooks to be used with all future mysqlnd connection */mysqlnd_uh_set_connection_proxy(new proxy());/* Create mysqli connection which is using the mysqlnd library */$mysqli = new mysqli("localhost", "root", "", "test");/* Example of a user API call which triggers the hooked mysqlnd call */var_dump($mysqli->change_user("root", "bar", "test"));?>
以上例程会输出：
proxy::changeUser(array ( 0 => NULL, 1 => 'root', 2 => 'bar', 3 => 'test', 4 => false, 5 => 3, )) proxy::changeUser returns false bool(false)
