In what ways can PHP be optimized for improved performance in a Webmail application?

To optimize PHP for improved performance in a Webmail application, one can utilize techniques such as caching, minimizing database queries, using efficient algorithms, and optimizing code structure. These optimizations can help reduce server load, decrease response times, and enhance overall user experience. 

// Example of optimizing PHP code by caching database queries
$cache_key = 'emails_' . $user_id;
$emails = apc_fetch($cache_key);

if (!$emails) {
    $emails = fetch_emails_from_database($user_id);
    apc_store($cache_key, $emails, 3600); // Cache for 1 hour
}

foreach ($emails as $email) {
    // Process email data
}
