db2_close --  Closes a database connection

说明

bool db2_close ( resource connection )

警告

本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

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。

例

例子 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.
