What are the potential drawbacks of using session_start() on every page in a PHP application?

Using session_start() on every page in a PHP application can potentially lead to performance issues, as it initializes a session on every page load, even if it's not necessary. To solve this, you can simply check if a session has already been started before calling session_start(). 

if (session_status() == PHP_SESSION_NONE) {
    session_start();
}
