php使用redis有序列表zadd批量添加的方法

# 添加单个元素

redis> ZADD page_rank 10 google.com
(integer) 1

# 添加多个元素

redis> ZADD page_rank 9 baidu.com 8 bing.com
(integer) 2

redis> ZRANGE page_rank 0 -1 WITHSCORES
1) "bing.com"
2) "8"
3) "baidu.com"
4) "9"
5) "google.com"
6) "10"

foreach($this->hashes as $k => $v) {

}

// sorted sets
foreach($this->zsets as $k => $v) {

}
//注意上面的代码
}

call_user_func_array(array($this->redis, 'zadd'), array('key', 0, 'we', 2, 'me', 3, 'td', 8, 'go'));
//array第一项是这个有序列表的键，后续的项目是排序权重，和值的交替
