Проверка статуса пользователя в MSN

Класс позволяет проверить онлайн-статус пользователя в MSN.

Результат проверки - TRUE, если пользователь в сети, или FALSE - если не в сети.

MSN:


/**
* This is an attempt to check online status for users.
* Method:
* first we ping an onlinestatus server. If response time is too long, or if it's down, we change.
* Time response has to be under 1s.
*
* You can find some address here: http://www.onlinestatus.org/usage.php
*
* I've seen that IP addresses are faster than "human" addresses, as we don't have to resolve these adresses.
*
* getStatus() sets status to :
* 0 : offline
* 1 : online
* 2 : unknown
*
* isOnline() returns true only if status is 1
*
* Requiered:
* 1- fsockopen support
