redis 简单应用

Incr

$views = Redis::incr('views');
$article_views = Redis::incr('article:' . $article_id . ':views');

zIncrBy  有序集合 

Sorted sets

    public function set($id){Redis::zIncrBy('articleViews', 1, 'article:'.$id);}public function get(){$hots = Redis::zRevRange('articleViews', 0, -1);foreach($hots as $index => $hot){$id    = str_replace('article:', '', $hot);$views = Redis::zScore('articleViews', $hot);echo $index+1 . ')'. 'the article id is '.$id.', it has '.$views.' views<br>';}}

Cache 缓存

    public function show(){return Cache::remember('post_cache', 1, function () {return Post::first();});}
