odbc_autocommit — Toggle autocommit behaviour

### 说明

odbc_autocommit ( resource `$connection_id` [, bool `$OnOff` = `FALSE` ] ) : mixed

Toggles autocommit behaviour.

By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.

### 参数

`connection_id`

  ODBC 连接标识符，详见 odbc_connect()。

`OnOff`

  If `OnOff` is `TRUE`, auto-commit is enabled, if it is `FALSE` auto-commit is disabled.

### 返回值

Without the `OnOff` parameter, this function returns auto-commit status for `connection_id`. Non-zero is returned if auto-commit is on, 0 if it is off, or `FALSE` if an error occurs.

If `OnOff` is set, this function returns `TRUE` on success and `FALSE` on failure.
