How can a PHP developer efficiently handle version checking for multiple game servers using Steam Web API and app IDs?

To efficiently handle version checking for multiple game servers using Steam Web API and app IDs, a PHP developer can create a function that retrieves the latest version number for each game server by making API requests to Steam. This function can be called periodically to check for updates and compare them with the current version of each server. By storing the latest version numbers in a database or cache, the developer can quickly determine if any updates are needed.

function checkServerVersions($appIds) {
    foreach ($appIds as $appId) {
        $url = "https://api.steampowered.com/ISteamApps/UpToDateCheck/v1/?appid={$appId}&version=1";
        $response = file_get_contents($url);
        $data = json_decode($response, true);
        
        $latestVersion = $data['response']['up_to_date'];
        
        // Compare latest version with current version of server and take appropriate action
        // Update database or send notification if update is needed
    }
}

// Example usage
$appIds = [730, 570, 440]; // Array of app IDs for game servers
checkServerVersions($appIds);
