How can PHP developers ensure that sessions are secure and not easily hijacked by malicious users?

To ensure that sessions are secure and not easily hijacked by malicious users, PHP developers can implement the following measures: 1. Use HTTPS to encrypt data transmission between the client and server. 2. Set session cookie parameters to secure and HttpOnly to prevent session hijacking and cross-site scripting attacks. 3. Regenerate session IDs after successful login to mitigate session fixation attacks.

// Enable secure and HttpOnly session cookies
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Regenerate session ID after successful login
session_regenerate_id(true);
