exemplu:

LOCK TABLE nested_category WRITE;

SELECT @myRight := rgt FROM nested_category
WHERE name = ‘TELEVISIONS’;

UPDATE nested_category SET rgt = rgt + 2 WHERE rgt > @myRight;
UPDATE nested_category SET lft = lft + 2 WHERE lft > @myRight;

INSERT INTO nested_category(name, lft, rgt) VALUES(‘GAME CONSOLES’, @myRight + 1, @myRight + 2);

UNLOCK TABLES;

SELECT CONCAT( REPEAT(‘ ‘, COUNT(parent.name) – 1), node.name) AS name
FROM nested_category AS node,
nested_category AS parent
WHERE node.lft BETWEEN parent.lft AND parent.rgt
GROUP BY node.name
ORDER BY node.lft;

ex:
$expire = time() + 30*24*60*60;
$credentials = serialize(array(“test”,”test”));
setcookie(“gloobal_user”, $credentials, $expire, “/wiki/”);

in pagina \inc\auth.php
functia auth_login

dupa instructiunea list($user,$sticky,$pass) = auth_getCookie();
citim din cookie username si parola utilizatorului care exista deja in wiki

$credentials = unserialize(str_replace(“\\”,”",$_COOKIE["gloobal_user"]));
$user = $credentials[0];
$pass = PMA_blowfish_encrypt($credentials[1],auth_cookiesalt());

Excerpt :

Think about what we might need a class like this for? We want to encrypt important data with a password for security reasons. We also want, as already mentioned, to be able to decrypt that data when necessary. Why should you use symmetric algorithms? It’s easy; when you’re offering a password sent via email or something like that, you need the password to be sent in plaintext. The hash algorithms are not reversible. Once you have hashed a string you can’t decipher the original text from the hash.
