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

如果成功则返回 TRUE，失败则返回 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.";
}
?>

上例将输出：

Connection was successfully closed.
