sure and most projects check the error_reporting() level against the $errno
like in the manual:
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting
        return;
    }

@ changes the error_reporting() level for that particular call, so those
custom error handler won't throw exceptions for the suppressed errors but
when you remove/nop @ their code would throwing stuff left and right.
