/**
* PHP error handler, converts all errors into ErrorExceptions. This handler
* respects error_reporting settings.
*
* @throws ErrorException
* @return TRUE
*/
public static function error_handler($code, $error, $file = NULL, $line = NULL)
{
    if (error_reporting() & $code)
    {
        // This error is not suppressed by current error reporting settings
        // Convert the error into an ErrorException
        throw new ErrorException($error, $code, 0, $file, $line);
    }

    // Do not execute the PHP error handler
    return TRUE;
