How can caching be implemented to reduce the number of database queries when checking for proxy server matches in PHP?

Caching can be implemented by storing the results of database queries in memory or a temporary storage to reduce the number of queries needed to check for proxy server matches in PHP. This can help improve performance by avoiding repeated database lookups for the same data. 

// Check if the result is already cached
$cacheKey = 'proxy_server_' . $ipAddress;
$proxyServer = apc_fetch($cacheKey);

// If not cached, query the database and store the result
if (!$proxyServer) {
    $query = "SELECT * FROM proxy_servers WHERE ip_address = '$ipAddress'";
    $result = mysqli_query($connection, $query);
    
    // Process the result and store it in cache
    $proxyServer = mysqli_fetch_assoc($result);
    apc_store($cacheKey, $proxyServer);
}

// Use the $proxyServer data as needed
