How can PHP developers optimize server resources when implementing frequent page updates?

One way PHP developers can optimize server resources when implementing frequent page updates is by implementing caching mechanisms. By caching frequently accessed data or rendered page content, the server can serve the content quickly without having to regenerate it each time a user requests the page. 

// Example of implementing caching in PHP using file-based caching

// Check if cached content exists
$cacheFile = 'cache/page1.html';
if (file_exists($cacheFile) && time() - filemtime($cacheFile) < 3600) {
    // Serve cached content
    include($cacheFile);
} else {
    // Generate and output new content
    ob_start();
    // Your code to generate page content here
    $content = ob_get_clean();
    
    // Save content to cache file
    file_put_contents($cacheFile, $content);
    
    // Output the generated content
    echo $content;
}
