What are some common best practices for handling errors or unexpected behavior in PHP functions?

When handling errors or unexpected behavior in PHP functions, it is important to use proper error handling techniques to ensure the stability and security of your application. Some common best practices include using try-catch blocks to catch exceptions, logging errors for debugging purposes, and providing meaningful error messages to users. 

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