php ci框架 查询mysql 返回json数组

Question

要获得的效果是：[{"name":"aaa","id":"1","sex","man"},{"name":"bbb","id":"2","sex","woman"},{}...]
现在的显示是{"name":"aaa","id":"1","sex","man"}{"name":"bbb","id":"2","sex","woman"}{}...
我的代码：
defined('BASEPATH')ORexit('Nodirectscriptaccessallowed');
classDemoextendsCI_Controller{
publicfunctionindex(){
$this->load->database();
$query=$this->db->query('SELECTname,id,sexFROMuser');
foreach($query->result()as$row){
echojson_encode($row);
}
}
}
我该如何修改?
