How can changes in ICQ's server configurations affect the functionality of PHP scripts designed to check online status?

Changes in ICQ's server configurations can affect the functionality of PHP scripts designed to check online status by causing connection issues or returning incorrect status information. To solve this issue, you can update the PHP script to use a more reliable method for checking online status, such as using a different API or service. 

// Example code using a different API to check online status
$userId = '123456789'; // ICQ user ID
$apiUrl = 'https://example.com/checkStatus?userId=' . $userId;

$status = file_get_contents($apiUrl);

if ($status === 'online') {
    echo 'User is online';
} else {
    echo 'User is offline';
}
