Are there any best practices or recommended libraries for integrating ICQ functionality in PHP?

To integrate ICQ functionality in PHP, one recommended library is the "php-icq-bot" library, which provides a simple way to interact with the ICQ network. This library allows you to send messages, set statuses, and perform other ICQ-related tasks within your PHP application.

// Include the php-icq-bot library
require 'vendor/autoload.php';

// Create a new ICQ bot instance
$bot = new Icq\Bot('your_icq_number', 'your_icq_password');

// Send a message to a specific ICQ user
$bot->sendMessage('123456789', 'Hello from PHP ICQ bot!');

// Set the bot's status
$bot->setStatus('Online');

// Get the bot's contact list
$contacts = $bot->getContacts();
