Join David Powers for an in-depth discussion in this video Using a trait to define common properties, part of PHP: Managing Persistent Sessions.
- [Voiceover] In chapter three…we created a class called MysqlSessionHandler.…Which implements the PHP SessionHandlerInterface.…This allows us to store session data…in Mysql or MariaDB.…For Persistent sessions,…the data needs to be copied to a separate database table.…Or it wont be liable to be garbage collected.…Rather than modify the MysqlSessionHandler class,…we'll extend it to create a new class…called PersistentSessionHandler.…The task of logging in users automatically…and retrieving their stored data,…will be handled by a separate class called Autologin.…
The PersistentSessionHandler and Autologin classes…work closely with each other,…and need to share common properties.…But they're not related in such a way…that Autologin could extend PersistentSessionHandler.…To simplify the definition of common properties,…we'll use a Trait called PersistentProperties.…If you're not familiar with Traits…they were introduced in PHP5.4.…They can be regarded as class fragments…that define properties and/or methods…for reuse in other classes.…
