Laravel，使用内存数据库缓存结果

Question

On News Website, I have an Article model, and I want to cache the latest articles since I expect they have the highest hits. How can I write a method that operates in this way:

public function findById($id)
{
    if(Article::inMemory($id))
        return Article::findFromMemory($id);

    return Article::find($id);
}

If there are any better approaches, please mention them as well

Answer 1

use Cache;
public function findById($id) 
{
    if ($articleInCache = Cache::get('article-' . $id)) {
        return $articleInCache;
    }
    return Article::find($id);
}

There are multiple memory drivers you can use and you can determine how you want to store the values in memory. Above, it assumes you stored the value with the 'article-' . $id (such as "article-5" as the key). It's up to you.
