How can PHP scripts be optimized to efficiently handle real-time updates without overloading the server or database?

To efficiently handle real-time updates without overloading the server or database, PHP scripts can be optimized by implementing techniques such as using caching mechanisms, minimizing database queries, optimizing code logic, and utilizing asynchronous processing. By reducing unnecessary database calls and optimizing code execution, the server load can be minimized, allowing for smoother real-time updates. 

// Example PHP code snippet demonstrating optimized handling of real-time updates
// Implementing caching mechanism to reduce database queries
$cacheKey = 'real_time_data';
$realTimeData = getFromCache($cacheKey);

if (!$realTimeData) {
    $realTimeData = fetchDataFromDatabase();
    saveToCache($cacheKey, $realTimeData);
}

// Process real-time updates asynchronously
$realTimeUpdate = $_POST['real_time_update'];
processRealTimeUpdate($realTimeUpdate);

// Function to get data from cache
function getFromCache($key) {
    // Implement caching mechanism here
}

// Function to fetch data from database
function fetchDataFromDatabase() {
    // Implement database query here
}

// Function to save data to cache
function saveToCache($key, $data) {
    // Implement caching mechanism here
}

// Function to process real-time updates asynchronously
function processRealTimeUpdate($data) {
    // Implement asynchronous processing logic here
}
