Using Error Control Operators to allow try catch to handle errors

Question

There are a few functions in php that throw errors when they fail, such as ftp_login. If I have this code.

try {
    $result = ftp_login($conn_id, $ftp_user_name, 'incorrectPassword');
    if (!$result) {
        throw new Exception('Could not login.');
    }
} catch (Exception $e) {
    echo $e->getMessage() . ' - ' . error_get_last();
}

It will not catch because of the error. Is the appropriate thing in this case to use an Error Control Operator like so?

try {
    $result = @ftp_login($conn_id, $ftp_user_name, 'incorrectPassword');
    if (!$result) {
        throw new Exception('Could not login.');
    }
} catch (Exception $e) {
    echo $e->getMessage() . ' - ' . error_get_last();
}

This allows me to react to the error, however it suppresses errors and would be a major performance hit. How can I judge which is the right approach, and is there any other alternatives I'm not considering?

Answer 1

Register your own error handler with set_error_handler. Within that error handler, throw the exception.

If now ftp_open throws an error, the exception from your custom error handler behave just as if ftp_open threw it.
