What are some considerations for optimizing performance and scalability when using PHP to manage multiple forums?

To optimize performance and scalability when managing multiple forums using PHP, consider implementing caching mechanisms to reduce database queries, optimizing code to minimize processing time, and using a load balancer to distribute traffic evenly across multiple servers. 

// Example of implementing caching with memcached

$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

$forums = $memcached->get('forums');

if (!$forums) {
    $forums = // Code to fetch forums data from database
    $memcached->set('forums', $forums, 3600); // Cache for 1 hour
}

// Use $forums data for forum management
