What are some best practices for changing cache intervals in PHP scripts?

When changing cache intervals in PHP scripts, it is important to carefully consider the impact on performance and resource usage. It is recommended to use cache intervals that balance the need for up-to-date data with the benefits of caching. Additionally, it is good practice to monitor the performance of the script after changing cache intervals to ensure optimal performance. 

// Example of changing cache interval in PHP script
$cacheKey = 'example_data';
$cacheTime = 3600; // 1 hour cache interval

// Check if data is cached
if ($cachedData = apc_fetch($cacheKey)) {
    // Use cached data
    $data = $cachedData;
} else {
    // Fetch data from database or external source
    $data = fetchData();

    // Cache data for specified interval
    apc_store($cacheKey, $data, $cacheTime);
}

// Use $data in script
echo $data;
