In what scenarios would it be beneficial to use functions to handle session management in PHP?
Using functions to handle session management in PHP can be beneficial in scenarios where you need to perform common session-related tasks repeatedly, such as starting a session, setting session variables, checking if a user is logged in, and destroying a session. By encapsulating these tasks in functions, you can easily reuse them throughout your codebase and ensure consistency in session handling.
// Function to start a session
function start_session() {
if (session_status() == PHP_SESSION_NONE) {
session_start();
}
}
// Function to set a session variable
function set_session_variable($key, $value) {
$_SESSION[$key] = $value;
}
// Function to check if a user is logged in
function is_logged_in() {
return isset($_SESSION['user_id']);
}
// Function to destroy a session
function destroy_session() {
session_unset();
session_destroy();
}
