Fatal error: Class 'SQLite3' not found

[John Gelm]

Running 8.04 64bit desktop w/LAMP added and would like to try out SQLite3 with PHP.

I get the error when running the example from:
http://us.php.net/manual/en/sqlite3.open.php

as follows:

root@voyager:/var/www/foliofn# cat example.php; php example.php
<?php
$db = new SQLite3('mysqlitedb.db');

$db->exec('CREATE TABLE foo (bar STRING)');
$db->exec("INSERT INTO foo (bar) VALUES ('This is a test')");

$result = $db->query('SELECT bar FROM foo');
var_dump($result->fetchArray());
?>

Fatal error: Class 'SQLite3' not found in /var/www/foliofn/example.php on line 2
root@voyager:/var/www/foliofn#

I have used synaptic to install anything I could find related to SQLite/SQLite3.

Any Ideas?

John
