What are some alternative approaches to storing and retrieving calculated values in PHP without using tables?

Storing and retrieving calculated values in PHP without using tables can be achieved by using caching mechanisms such as PHP's built-in APCu or Memcached. These caching solutions allow you to store calculated values in memory for faster retrieval without the need for a database table. 

// Using APCu for caching calculated values
$key = 'calculated_value';
$cache_value = apcu_fetch($key);

if (!$cache_value) {
    // Calculate the value if it's not in the cache
    $value = 10 * 5;
    
    // Store the calculated value in the cache
    apcu_store($key, $value);
    
    // Use the calculated value
    echo $value;
} else {
    // Use the cached value
    echo $cache_value;
}
