db2_close — Closes a database connection

说明

bool db2_close ( resource $connection )

This function closes a DB2 client connection created with db2_connect() and returns the corresponding resources to the database server.

If you attempt to close a persistent DB2 client connection created with db2_pconnect() , the close request is ignored and the persistent DB2 client connection remains available for the next caller.

参数

connection: Specifies an active DB2 client connection.

返回值

成功时返回 TRUE ，或者在失败时返回 FALSE 。

范例

Example #1 Closing a connection

The following example demonstrates a successful attempt to close a connection to an IBM DB2, Cloudscape, or Apache Derby database.

  <?php
$conn  =  db2_connect ( 'SAMPLE' ,  'db2inst1' ,  'ibmdb2' );
 $rc  =  db2_close ( $conn );
if ( $rc ) {
    echo  "Connection was successfully closed." ;
}
 ?>

以上例程会输出：

Connection was successfully closed.
