What strategies can PHP developers employ to improve the performance and user experience of a webpage displaying dynamic content generated by PHP scripts?

One strategy PHP developers can employ to improve the performance and user experience of a webpage displaying dynamic content generated by PHP scripts is to implement caching. By caching the generated content, the server can serve the same content to multiple users without having to regenerate it each time, reducing server load and improving page load times. 

// Example of caching dynamic content in PHP
$cache_key = 'dynamic_content_' . md5($query_params); // Generate a unique cache key based on query parameters
$cache_duration = 3600; // Cache content for 1 hour

if ($cached_content = apc_fetch($cache_key)) {
    echo $cached_content; // Output cached content if available
} else {
    ob_start(); // Start output buffering
    // Generate dynamic content here
    $dynamic_content = generate_dynamic_content($query_params);
    echo $dynamic_content;
    $cached_content = ob_get_clean();
    apc_store($cache_key, $cached_content, $cache_duration); // Cache the generated content
}
