What are the implications of running resource-intensive scripts frequently on a web server in terms of server performance and stability?

Running resource-intensive scripts frequently on a web server can lead to decreased server performance and stability. This can result in slower response times for users, potential crashes or downtime, and increased server costs. To mitigate this issue, it is important to optimize the scripts, use caching mechanisms, and consider offloading intensive tasks to background processes. 

// Example of optimizing a resource-intensive script by implementing caching

// Check if the result is already cached
$cache_key = 'resource_intensive_data';
$cache_result = get_from_cache($cache_key);

if ($cache_result) {
    // Use the cached result
    echo $cache_result;
} else {
    // Run the resource-intensive script
    $result = run_resource_intensive_script();

    // Save the result to cache
    save_to_cache($cache_key, $result);

    // Output the result
    echo $result;
}

function get_from_cache($key) {
    // Implement cache retrieval logic
}

function save_to_cache($key, $data) {
    // Implement cache saving logic
}

function run_resource_intensive_script() {
    // Implement resource-intensive script logic
}
