复制代码 代码如下:

$redis = new redis(); 
$redis->connect('192.168.1.108', 6379); 
$redis->delete('test'); 
$redis->zadd('test', 1, 'val1'); 
$redis->zadd('test', 0, 'val2'); 
$redis->zadd('test', 3, 'val3'); 
 
print_r($redis->zrange('test', 0, -1)); //结果：Array ( [0] => val2 [1] => val1 [2] => val3 ) 
 
$redis->zdelete('test', 'val2'); 
print_r($redis->zrange('test', 0, -1)); //结果：Array ( [0] => val1 [1] => val3 )  
 
$redis->zadd('test',4, 'val0'); 
print_r($redis->zrevrange('test', 0, -1));  //结果：Array ( [0] => val0 [1] => val3 [2] => val1 ) 
print_r($redis->zrevrange('test', 0, -1,true));  //结果：Array ( [val0] => 4 [val3] => 3 [val1] => 1 )  
 
echo "<br>"; 
$redis->zadd('key', 0, 'val0'); 
$redis->zadd('key', 2, 'val2'); 
$redis->zadd('key', 10, 'val10'); 
 
print_r($redis->zrangebyscore('key', 0, 3, array('limit' => array(1, 1),'withscores' => TRUE))); //结果：Array ( [val2] => 2 ) 
print_r($redis->zrangebyscore('key', 0, 3, array('limit' => array(1, 1)))); //结果：Array ( [0] => val2 )  
 
echo $redis->zcount('key', 0, 3); //结果：2 
 
$redis->zremrangebyscore('key', 0, 3); 
print_r($redis->zrange('key', 0, -1));  //结果：Array ( [0] => val10 )  
 
echo $redis->zsize('key');   //结果：1 
 
$redis->zadd('key', 2.5, 'aaaa'); 
echo $redis->zscore('key', 'aaaa');   //结果：2.5 
 
echo $redis->zrank('key', 'aaaa');   //结果：0 
echo $redis->zrevrank('key', 'aaaa');    //结果：1
