More Information More Information
- Data might need to be serialized to allow it to be successfully stored and retrieved from a database in a form that PHP can understand.
- Confusingly, strings that contain already serialized values are serialized again, resulting in a nested serialization. Other strings are unmodified.
- A possible solution to prevent nested serialization is to check if a variable is serialized using is_serialized()
if( !is_serialized( $data ) ) { $data = maybe_serialize($data); }
