[SOLVED] Pear DB self instantiation

[Lodius2000]

instantiation (I think I spelled that right)

 

any way, as far as I can tell Pear db self instantiates, meaning there is not line (that I type) that says

 

$db = new db;

 

heres my login script as an example

 

<?php
include('path/to/pear/db.php');

$user     = '**********';
$password = '*********';
$hostspec = 'localhost';
$database = ''*********';

$phptype = 'mysql';

$dsn = "$phptype://$user:$password@$hostspec/$database";

//establish the connection
$db =& DB::connect($dsn);
if (DB::isError($db)){
die ($db->getMessage());
}
?>

 

this works fine and uses methods of the db object, but I have not made an object called $db from any class....How does it work?

[Lodius2000]

I know $database has an extra single quote in it... I spotted it too late to edit, please disregard

[trq]

DB::connect() is a static method which returns a database object as defined by the $dsn string passed to it.

See explanation of design patterns in PHP manual to see similar technique used.
