How can caching be implemented to avoid hitting the Amazon API limit in PHP?

To avoid hitting the Amazon API limit in PHP, caching can be implemented to store the API responses and reuse them instead of making repeated requests to the API. This can help reduce the number of API calls and prevent hitting the rate limit imposed by Amazon. 

// Check if the response is already cached
$cacheKey = md5($apiEndpoint);
$cacheFile = 'cache/' . $cacheKey . '.json';

if (file_exists($cacheFile) && time() - filemtime($cacheFile) < 3600) {
    $response = file_get_contents($cacheFile);
} else {
    // Make API request
    $response = file_get_contents($apiEndpoint);
    
    // Cache the response
    file_put_contents($cacheFile, $response);
}

// Process the API response
$data = json_decode($response, true);
