php正则匹配截取json

Question

请教一个正则截取问题$script='cgiData={pageIdx:0,pageCount:1,pageSize:100,groupsList:({"groups":[{"id":0,"name":"未分组","cnt":16},{"id":1,"name":"黑名单","cnt":0},{"id":2,"name":"星标组","cnt":0}]}).groups,friendsList:({"contacts":[{"id":6,"nick_name":"yan","remark_name":"","group_id":0},{"id":8,"nick_name":"mm","remark_name":"","group_id":0},{"id":4,"nick_name":"gg","remark_name":"","group_id":0},{"id":2,"nick_name":"sa","remark_name":"","group_id":0}]}).contacts,currentGroupId:0,type:0,userRole:1*1,verifyMsgCount:*1};seajs.use("user/index");';怎么把contacts中间的[{"id":6,"nickname":"yan","remarkname":"","groupid":0},{"id":8,"nickname":"mm","remarkname":"","groupid":0},{"id":4,"nickname":"gg","remarkname":"","groupid":0},{"id":2,"nickname":"sa","remarkname":"","groupid":0}]这段截取出来？

PHP的DEMO：
preg_match_all("/\[{.*?\}]/is",$script,$matches);
$result=json_decode($matches[0][1]);
这个正则不是最佳方案，不过结果是你想要的就是。
