Описание

Constructor for the authentication system.

The constructor will ensure that the PHP session management is started by calling session_start(). This is done as Auth requires a session to be active to operate correctly.

Пример

<?php
require_once "Auth/Auth.php";

function myOutput($username, $status, $auth)
{
    ...  /* See first example in introduction for the full listing */
}

$params = array(
            "dsn" => "mysql://martin:test@localhost/auth",
            "table" => "myAuth",
            "usernamecol" => "myUserColumn",
            "passwordcol" => "myPasswordColumn"
            );

$a = new Auth("DB", $params, "myOutput");

$a->start();

if ($a->getAuth()) {
    echo "You have been authenticated successfully.";
}
?>

This example shows you how you can specifiy alternative names for the database table and the column names. In our example, we use the table myAuth, select the username from the field myUserColumn and the password from the field myPasswordColumn. The default values for this fields are auth, username and password. Note that you can also specify an existing DB object with the dsn parameter instead of a DSN.

This feature is necessary if you want to use PEAR::Auth with a database layout that is different from the one PEAR::Auth uses by default.

Пример

<?php
require_once "Auth/Auth.php";

function myOutput($username, $status)
{
    ...  /* See first example in introduction for the full listing */
}

$a = new Auth(new CustomAuthContainer($options), null, "myOutput");

$a->start();

if ($a->getAuth()) {
    echo "You have been authenticated successfully.";
}
?>

This example shows you how you can pass your own storage container to Auth.

If the storage containers supplied with Auth are not capable of fulfilling your requirements, you can easliy create your own storage container. Read the storage containers section for more info Introduction - The storage drivers
