# db2_pclose

(PECL ibm_db2 >= 1.8.0)

db2_pclose — Closes a persistent database connection

### 설명

bool db2_pclose ( resource `$resource` )

This function closes a DB2 client connection created with db2_pconnect() and returns the corresponding resources to the database server.

> Note: This function is only available on i5/OS in response to i5/OS system administration requests.

If you have a persistent DB2 client connection created with db2_pconnect(), you may use this function to close the connection. To avoid substantial connection performance penalties, this function should only be used in rare cases when the persistent connection has become unresponsive or the persistent connection will not be needed for a long period of time.

### 인수

`connection`

  Specifies an active DB2 client connection.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 예제

}
?>`
