What are some best practices for implementing caching in PHP when using automated content generation?

When using automated content generation in PHP, implementing caching can help improve performance by storing generated content and serving it quickly without the need to regenerate it each time. One best practice is to use a key-value store like Redis or Memcached to store cached content. Another best practice is to set an appropriate expiration time for cached content to ensure it stays up to date. Additionally, consider using a caching library like Symfony Cache or Laravel Cache for easier implementation and management. 

// Example of caching generated content using Redis in PHP

// Connect to Redis server
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

// Generate a unique cache key based on the content being generated
$cacheKey = 'generated_content_' . md5($input);

// Check if content is already cached
$cachedContent = $redis->get($cacheKey);

if ($cachedContent === false) {
    // Content is not cached, generate it
    $generatedContent = generateContent($input);

    // Store generated content in cache with an expiration time of 1 hour
    $redis->set($cacheKey, $generatedContent, 3600);

    // Return generated content
    echo $generatedContent;
} else {
    // Content is cached, return it
    echo $cachedContent;
}
