What are some best practices for handling errors and terminating functions in PHP without using exit()?

When handling errors and terminating functions in PHP, it's best practice to use exceptions instead of using exit() to gracefully handle errors and allow for better error handling and debugging. By throwing exceptions, you can catch them in a try-catch block and handle the error in a more controlled manner. 

try {
    // Code that may throw an exception
    if ($errorCondition) {
        throw new Exception('An error occurred');
    }
} catch (Exception $e) {
    // Handle the error
    echo 'Error: ' . $e->getMessage();
}
