How can session variables be properly managed to prevent them from affecting each other on different pages or tabs?

Session variables can be properly managed by using unique session names for each page or tab. This can be achieved by setting a custom session name based on the page or tab identifier. By doing so, each page or tab will have its own separate session data, preventing them from affecting each other.

// Set a unique session name based on page or tab identifier
session_name("page1_session");
session_start();

// Access and manipulate session variables as needed
$_SESSION['variable'] = "value";
