I have mysql table with collumns like \'operation.date\', \'operation.name\' and etc.
After fetching that table data as object with $mysqli->fetch_object() i
Specify aliases in your SQL query like SELECT column AS nameWithoutDots ...
or access these properties with $object->{'operation.name'}
or cast the object to array like this: $obj = (array)$obj; echo $obj['operation.name'].
