Function Reference/maybe serialize
Description
Serialize data, if needed.
Usage
<?php maybe_serialize( $data ); ?>
Parameters
- $data
- (mixed) (required) Data that might be serialized.
- Default: None
Return Values
- (mixed)
- A scalar data
Examples
Notes
- 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
<?php if(!is_serialized( $data )) { $data = maybe_serialize($data); } ?>
