怎么用正则把中间的[]截取出来。现在这样没办法用json_decode，求帮忙。

不能用 json_decode ?! 书少勿骗：http://3v4l.org/pigFV

不关心能否json_decode，只给出正则

<code>/\[([^\]]+)\]/
</code>

取第一个组即可

不知道具体应用场景。提供以下两种方式：
1.可以直接用json_decode(),转换为数组，直接提取需要的信息，更简单、方便。
可参考：http://php.net/manual/zh/function.json-decode.php
2.如果只提取[]之间的部分，匹配模式：'/[(.*?)]/is'; 然后再json_decode.其事，第一种方式，就可以了
