How can caching be implemented in PHP to store and retrieve manipulated HTML data for faster loading times?

Caching in PHP can be implemented using techniques like storing manipulated HTML data in a file or using a caching library like Memcached or Redis. By caching the HTML data, subsequent requests can retrieve the cached data instead of regenerating it, resulting in faster loading times for the web application. 

// Check if cached data exists
$cacheFile = 'cached_data.html';
if (file_exists($cacheFile) && time() - filemtime($cacheFile) < 3600) {
    // Output cached data
    readfile($cacheFile);
} else {
    // Generate HTML data
    ob_start();
    // Manipulate and output HTML data here
    $htmlData = ob_get_clean();
    
    // Store manipulated HTML data in cache file
    file_put_contents($cacheFile, $htmlData);
    
    // Output HTML data
    echo $htmlData;
}
