How can PHP developers prevent conflicts and unintended changes to session data when working with multiple modules or team members?

To prevent conflicts and unintended changes to session data when working with multiple modules or team members, PHP developers can namespace their session variables based on the module or team member to ensure uniqueness. This can be achieved by prefixing session variable names with a specific identifier for each module or team member. 

// Module A session variables
$_SESSION['moduleA_user_id'] = 123;
$_SESSION['moduleA_username'] = 'john_doe';

// Module B session variables
$_SESSION['moduleB_user_id'] = 456;
$_SESSION['moduleB_username'] = 'jane_smith';
