What are the potential security risks associated with modifying session handling manually in PHP to accommodate specific client requests?

Modifying session handling manually in PHP to accommodate specific client requests can introduce security risks such as session fixation, session hijacking, and session data tampering. To mitigate these risks, it is recommended to use secure session handling techniques such as using HTTPS, generating unique session IDs, and validating session data on each request. 

// Start secure session
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true,
    'samesite' => 'Strict'
]);
session_start();
