# Configuración en tiempo de ejecución

El comportamiento de estas funciones se ve afectado por la configuración de php.ini.

Opciones de configuración de mongodb
Nombre | Por defecto | Cambiable | Historial de cambios
--- | --- | --- | ---
mongodb.debug | "" | `INI_ALL` |
mongodb.mock_service_id | "0" | `INI_ALL` | Disponible desde mongodb 1.11.0.

He aquí una breve explicación de las directivas de configuración.

`mongodb.debug` string

  This option can be used to enable or disable trace-level debug logging in the driver (and libmongoc).

  Specify an empty string, `"0"`, `"off"`, `"no"`, or `"false"` to disable logging.

  Specify `"stderr"` or `"stdout"` to log to `stderr` or `stdout`, respectively.

  Specify `"1"`, `"on"`, `"yes"`, or `"true"` to log to a new temporary file within the default system temp directory (i.e. sys_get_temp_dir()).

  Specify any other string to log to a new temporary file within that directory. If the directory cannot be used, the default system temp directory will be used instead.

  > Nota:

  > Please note that the debug log can contain sensitive information, such as credentials to the MongoDB server and full documents written to or read from the server. Please review any debug logs before sharing them with other people.

`mongodb.mock_service_id` string

  This option can be used to enable or disable mocking of the `serviceId` field in `hello` command responses.

  Specify an empty string, `"0"`, `"off"`, `"no"`, or `"false"` to disable mocking.

  Specify `"1"`, `"on"`, `"yes"`, or `"true"` to enable mocking.

  > Nota:

  > This option is primarily intended for internal testing of load balancers and should not be used under normal circumstances.
