How does the use of HTTPS affect session transmission in PHP, and what are common problems associated with it?

Using HTTPS ensures that data transmitted between the client and server is encrypted, providing a secure connection. This helps protect sensitive information such as login credentials, personal details, and payment information from being intercepted by malicious actors. Common problems associated with HTTPS include mixed content warnings, certificate errors, and performance overhead due to encryption and decryption processes. 

// Force HTTPS in PHP
if ($_SERVER['HTTPS'] != 'on') {
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}
