Are there any best practices for implementing ICQ online status checking in PHP?

One best practice for implementing ICQ online status checking in PHP is to use the official ICQ API provided by ICQ. This API allows you to check the online status of a user by sending a request to their server.

// Set the ICQ user ID
$icqUserId = '123456789';

// Send a request to the ICQ API to check the online status
$response = file_get_contents('https://api.icq.net/bot/v1/users/' . $icqUserId);

// Decode the JSON response
$data = json_decode($response, true);

// Check if the user is online
if ($data['online']) {
    echo 'User is online';
} else {
    echo 'User is offline';
}
