Auth_Container_MDB2

Auth_Container_MDB2 -- Authenticate against a database using MDB2

MDB2 Container

This container makes use of PEAR::MDB2 abstraction layer for database access. That means that you can use all databases that are supported by the MDB2 abstraction layer to store the login data.

The storage-specific argument for the Auth constructor() is an array of options.

Заметка

By default, MDB2's default portability setting of MDB2_PORTABILITY_ALL is used. This setting may cause unexpected behaviour, such as field names being converted to lowercase regardless of their definition in the database schema. The "db_options" option can be used to override this, as shown in the following example.

Пример 29-1. Example overriding MDB2's default portability

$options = array('dsn'         => 'mysql://user:password@localhost/database',
                 'usernamecol' => 'UserName',
                 'passwordcol' => 'PassWord',
                 'db_options'  => array('portability' => MDB2_PORTABILITY_ALL ^ MDB2_PORTABILITY_FIX_CASE)
                );
$auth = new Auth('MDB2', $options, 'loginFunction');
