通过php代码去弄 总是会被序列化

127.0.0.1:6379> ZRANGE key  0 -1 WITHSCORES
1) "i:1;"
2) "1"
3) "s:6:\"google\";"
4) "1"
5) "i:4;"
6) "2"
7) "s:4:\"i:1;\";"
8) "2"
127.0.0.1:6379> ZRANGE key  0 -1 WITHSCORES

但是 我在cli下 可以直接添加正常. 这是为什么?

127.0.0.1:6379> zadd key 1 google
(integer) 1
127.0.0.1:6379> ZRANGE key  0 -1 WITHSCORES
 1) "google"
 2) "1"
 3) "i:1;"
 4) "1"
 5) "s:6:\"google\";"
 6) "1"
 7) "i:4;"
 8) "2"
 9) "s:4:\"i:1;\";"
10) "2"
127.0.0.1:6379>
