本文实例为大家分享了PHP实现文章发布系统、用户投票系统的具体代码，供大家参考，具体内容如下

redis; $key= "queue"; $ONE_WEEK_IN_SECONDS= 7*86400; $redis -> multi($key); //生成新的文章id $article_id = $redis -> incr("article:",$key);

//<a href="https://www.jb51.cc/tag/wenzhang/" target="_blank" class="keywords">文章</a>已投票<a href="https://www.jb51.cc/tag/yonghuming/" target="_blank" class="keywords">用户名</a>单
$<a href="https://www.jb51.cc/tag/Vote/" target="_blank" class="keywords">Vote</a>d = "<a href="https://www.jb51.cc/tag/Vote/" target="_blank" class="keywords">Vote</a>d:".$article_id;
$this->re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a>->sadd($<a href="https://www.jb51.cc/tag/Vote/" target="_blank" class="keywords">Vote</a>d,$user,$key);
//设置过期时间(为1周)
$this->re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a>->expipre($<a href="https://www.jb51.cc/tag/Vote/" target="_blank" class="keywords">Vote</a>d,$ONE_WEEK_IN_SECONDS,$key);

//<a href="https://www.jb51.cc/tag/huoqu/" target="_blank" class="keywords">获取</a>现在的时间
$<a href="https://www.jb51.cc/tag/Now/" target="_blank" class="keywords">Now</a> =time();
$article = "article:".$article_id;
$data = ['title'=>'测试1','link'=>'www.hahaha.com','poster'=>$user,'tine'=>$<a href="https://www.jb51.cc/tag/Now/" target="_blank" class="keywords">Now</a>,'<a href="https://www.jb51.cc/tag/Vote/" target="_blank" class="keywords">Vote</a>s'=>1];
//$data = json_encode($data);
$re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a> -> hmset($article,$data,$key);

//将<a href="https://www.jb51.cc/tag/wenzhang/" target="_blank" class="keywords">文章</a><a href="https://www.jb51.cc/tag/tianjia/" target="_blank" class="keywords">添加</a>到根据时间排序有序集合和根据评分排序有序结合中
$this -> re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a> -> zadd("<a href="https://www.jb51.cc/tag/score/" target="_blank" class="keywords">score</a>:",1,$article,$key);
$this -> re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a> -> zadd("time:",$<a href="https://www.jb51.cc/tag/Now/" target="_blank" class="keywords">Now</a>,$key);

$re<a href="https://www.jb51.cc/tag/dis/" target="_blank" class="keywords">dis</a> -> exec($key);

}
