如上图所示，select()方法查出的全部为字符型数组输出，有没有办法让它按数据库的字段类型输出，要不起码该是整型的输出整型的。
因为要转为JSON，特殊需求必须该整型的就整型数据，
在此求助，谢谢！
直接 json_encode 就变成
[{"id":"1","fid":"0","name":"\u7535\u8111","url":"#","target":"_blank","level":"1","sort":"1","status":"1"},{"id":"2","fid":"1","name":"CPU","url":"#","target":"_blank","level":"2","sort":"1","status":"1"},{"id":"3","fid":"1","name":"\u786c\u76d8","url":"#","target":"_blank","level":"2","sort":"2","status":"1"}]
可是需要的结果如下:
[{"id":1,"fid":0,"name":"\u7535\u8111","url":"#","target":"_blank","level":1,sort":1,"status":1},{"id":2,"fid":1,"name":"CPU","url":"#","target":"_blank","level":2,"sort":1,"status":1},{"id":3,"fid":1,"name":"\u786c\u76d8","url":"#","target":"_blank","level":2,"sort":2,"status":1}]
整型的不要引号
