# msql_close

(PHP 4, PHP 5, PHP 7)

msql_close — Close mSQL connection

### 说明

msql_close ([ resource `$link_identifier` ] ) : bool

msql_close() closes the non-persistent connection to the mSQL server that's associated with the specified link identifier.

Using msql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution. See also freeing resources.

### 参数

`link_identifier`

  mSQL 连接。如果不指定，则使用由 msql_connect() 最近打开的连接。如果没有找到该连接，函数会尝试通过调用 msql_connect() 建立连接并使用它。

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。
