The Json_encode output value is not the same in laravel-php.

The array printed with Print_r is this:

Array(    [total] => 8    [rows] => Array        (            [0] => Array                (                    [id] => 1                    [email] => 379395979@qq.com                    [activated] => 1                    [username] => yuan                    [created_at] => 2014-03-04 02:30:43

Why use Json_encode output after the other data are good, only activated this field will turn 1 into a true,0 to false, has anyone encountered this situation? How to resolve to output the original value ...
Frame is Laravel4

JSON values like this:

{"total":8,"rows":[{"id":1,"email":"379395979@qq.com","activated":true,"activated_at":null,"last_login":"2014-04-03 05:41:30","username":"yuan","created_at":"2014-03-04 02:30:43"}

Using var_dump to see the type of data source, LZ printing results are different, the problem is in the data source, if the data table is not a problem, it should be from the database to obtain data from the data format is problematic.

json_encodeNo change bool in value
..
I just got the wrong idea.
Tested a bit, did not find json_encode a change ...
Laravel Source also did not find the conversion of the place.
