db2_close Closes a database connection

说明

db2_close ( resource $connection ) : bool

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.
