将 key 中储存的数字值增一。

<?php
//连接本地的 Redis 服务
$redis = new Redis();
$redis->connect('10.1.3.15', 6379);
$redis->auth('kuaicdn_redis_passwd');
$redis->flushAll();
$ret['exec'][]=$redis->mset(array(
    'list_test1'=>'5',
    'list_test2'=>5,
    'list_test3'=>5.1,
    'list_test4'=>'5.1',
    'list_test5'=>'a',
    'list_test6'=>'我'
));
$ret['ret']['a']=$redis->mget(array(
    "list_test1",
    "list_test2",
    "list_test3",
    "list_test4",
    "list_test5",
    "list_test6",
));
$ret['ret']['b'][]=$redis->incr('list_test1');
$ret['ret']['b'][]=$redis->incr('list_test2');
$ret['ret']['b'][]=$redis->incr('list_test3');
$ret['ret']['b'][]=$redis->incr('list_test4');
$ret['ret']['b'][]=$redis->incr('list_test5');
$ret['ret']['b'][]=$redis->incr('list_test6');
$ret['ret']['mget']=$redis->mget(array(
    "list_test1",
    "list_test2",
    "list_test3",
    "list_test4",
    "list_test5",
    "list_test6",
));
print_r($ret);
?>

返回值：

Array
(
    [exec] => Array
        (
            [0] => 1
        )
    [ret] => Array
        (
            [a] => Array
                (
                    [0] => 5
                    [1] => 5
                    [2] => 5.1
                    [3] => 5.1
                    [4] => a
                    [5] => 我
                )
            [b] => Array
                (
                    [0] => 6
                    [1] => 6
                    [2] => 
                    [3] => 
                    [4] => 
                    [5] => 
                )
            [mget] => Array
                (
                    [0] => 6
                    [1] => 6
                    [2] => 5.1
                    [3] => 5.1
                    [4] => a
                    [5] => 我
                )
        )
)

可以得出结论, 该函数只会影响整数
