Are there any best practices for utilizing Opcode Caches like APC or eAccelerator to improve PHP performance?

Utilizing Opcode Caches like APC or eAccelerator can significantly improve PHP performance by storing precompiled PHP code in memory, reducing the need for PHP to parse and compile scripts on each request. This can lead to faster execution times and reduced server load. 

// Example code snippet for utilizing APC cache in PHP
if (function_exists('apc_store')) {
    $key = 'cached_data';
    $data = apc_fetch($key);

    if ($data === false) {
        $data = // Your expensive computation or data retrieval logic here

        apc_store($key, $data, $ttl); // $ttl is the time-to-live for the cached data
    }

    // Make use of $data here
} else {
    // APC extension is not available, handle accordingly
}
