How should PHP developers approach error handling and displaying messages to users in their code?

PHP developers should use try-catch blocks to handle errors in their code and display user-friendly error messages when necessary. By catching exceptions and displaying custom error messages, developers can provide more helpful information to users and prevent exposing sensitive details about the application. It is also important to log errors to a secure location for debugging purposes. 

try {
    // Code that may throw an exception
} catch (Exception $e) {
    // Display a user-friendly error message
    echo "An error occurred. Please try again later.";
    
    // Log the error for debugging
    error_log($e->getMessage());
}
