How can PHP developers address session passing issues on different server configurations?

Session passing issues on different server configurations can be addressed by setting the session configuration to use a common storage mechanism, such as a database or Redis. This ensures that sessions are accessible across different servers, regardless of their configurations. 

// Set session save path to a common storage mechanism
session_save_path("/path/to/common/storage");

// Set session handler to use database or Redis
ini_set('session.save_handler', 'redis');
ini_set('session.save_path', 'tcp://127.0.0.1:6379');

// Start the session
session_start();
