    Just accept a ZVAL and do your appropriate conversion later

    It's a matter of

    switch(Z_TYPE_P(zval_container)) {
        case IS_STRING:
            // do appropriate conversion
            break;
        case IS_LONG:
            // everythings fine
            break;
        default:
            php_error(E_WARNING, "%s(): argument 1 must be integer or string", 
                      get_active_function_name(TSRMLS_C));
            RETURN_FALSE;
    }

    IMHO. Watch out, YMMV; HTH.
