Own, runtime error

//$r - ответ от БД
$r = $r->fetch_all();

Call to undefined method mysqli_result::fetch_all()

How is there no such method, if it IS ?

It is useful to read the documentation in its entirety, and not to the point of interest:

Check the $r variable - I'm sure it hasn't been assigned an object with that method.
