db2_close — Closes a database connection

### Description

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.

### Parameters

`connection`

  Specifies an active DB2 client connection.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

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.";
}
?>`

The above example will output:

    Connection was successfully closed.
