When you want to concatenate what the function returns print_r () you may need to specify the second parameter as true since this will cause a String to be returned and the concatenation to be done or assigned to a variable, otherwise it will return true or 1 , it would be correct to use this in the following way.
echo "<p> Result antes" . print_r($result,true);
$row = $result->fetch_assoc(); //{
echo "<p> Result despues" . print_r($result,true);
