What are the potential reasons for a session ID being renewed on reload in PHP?

When a session ID is being renewed on reload in PHP, it could be due to a misconfiguration in the server settings or the session handling code. To solve this issue, make sure that the session configuration is properly set up to maintain the session ID across page reloads. Additionally, ensure that the session_start() function is called at the beginning of each page that needs to access session variables.
