Is it advisable to use a caching mechanism for frequently queried tables in PHP applications?

Using a caching mechanism for frequently queried tables in PHP applications can significantly improve performance by reducing the number of database queries made. This is especially useful for tables that are queried frequently but don't change often. By caching the results of these queries, you can serve the data faster without hitting the database every time. 

// Example of using caching mechanism for frequently queried tables

// Check if the data is already cached
$cacheKey = 'frequently_queried_data';
$cachedData = apc_fetch($cacheKey);

if (!$cachedData) {
    // If data is not cached, fetch it from the database
    $data = // Your database query here

    // Cache the data for future use
    apc_store($cacheKey, $data, 3600); // Cache for 1 hour
} else {
    // Use the cached data
    $data = $cachedData;
}

// Use the $data variable for further processing
