使用php以这种格式返回json

Question

{
    code: "AL",
    z: 3204
}, {
    code: "DZ",
    z: 35468
}, 

试图返回类似的东西.我这样做:

$arr = array ('code'=>array('z'),'US'=>2233332,'c'=>3,'d'=>4,'e'=>5);

    echo json_encode($arr);

Answer 1

只需按照json格式化:

$foo = array(
    array(
       'code' => 'AL',
       'z' => 3204
    ),
    array(
       'code' => 'DZ',
       'z' => 35468
   )
);
