# mysql_close

(PHP 3, PHP 4 , PHP 5)

mysql_close -- Close MySQL connection

## Description

bool mysql_close ( [resource link_identifier])

成功回傳`TRUE`失敗回傳`FALSE`。

mysql_close() closes the connection to the MySQL server that's associated with the specified link identifier. If link_identifier isn't specified, the last opened link is used.

Using mysql_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.

> 備注: mysql_close() will not close persistent links created by mysql_pconnect().
