How can the return value of session_start() be effectively checked and utilized in PHP code for debugging purposes?

When using session_start() in PHP, it is important to check the return value to ensure that the session has started successfully. This can be done by checking if the return value is true or false. If session_start() returns true, the session has started successfully. If it returns false, there may be an issue with starting the session, such as headers already being sent. Checking and utilizing the return value of session_start() can help in debugging and resolving session-related issues. 

<?php
if(session_start()) {
    echo "Session started successfully";
} else {
    echo "Failed to start session";
}
?>
