What are some best practices for optimizing the performance of a website that heavily relies on PHP for dynamic content generation?

To optimize the performance of a website that heavily relies on PHP for dynamic content generation, it is important to minimize database queries, enable caching mechanisms, and optimize code execution. Additionally, utilizing opcode caching, implementing lazy loading for resources, and using asynchronous processing can help improve the overall performance of the website. 

// Enable opcode caching
opcache_enable();

// Implement lazy loading for resources
function lazy_load_images($image_path) {
    echo "<img loading='lazy' src='$image_path' alt=''>";
}

// Use asynchronous processing
function send_email_async($to, $subject, $message) {
    exec("php -f send_email.php $to $subject $message > /dev/null &");
}
