What are the potential consequences of using @ before PHP functions?

Using @ before PHP functions suppresses any error messages or warnings that the function may generate. This can make debugging more difficult as errors will not be displayed. Instead of using @ to suppress errors, it is better to handle potential errors using try-catch blocks or proper error handling mechanisms. 

try {
    $result = @some_function();
    if ($result === false) {
        throw new Exception('Error occurred in some_function');
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
