php object attribute with dot in name

Question

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

Answer 1

The correct way of accessing properties with a dot should be :

echo $object->{"operation.date"}

Answer 2

Change the sql to return valid property names using the 'as' feature

eg. select operation.date as date

Answer 3

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'].

Answer 4

To access these attributes you need to wrap them with curly brackets:

echo $object->{"operation.date"} //2010-12-15

If you set an attribute this way the offending symbol gets removed, allowing you to access the attribute as echo $object->operationdate //2010-12-15

Answer 5

You can get assoc array instead object by using $mysqli->fetch_assoc()
