Question

我有一个数组，我想将它转换为json，但它为一个字段返回null，这是我的阵列：

 [workname] => IŞIKLAR MÜHENDİSLİK
 [workno] => 22330
 [workdate] => Array
    (
     [0] => Array
        (
         [date] => 
         [type] => ELEKTRİK
        )

     [1] => Array
        (
         [date] => 31.12.2007
         [type] => ELEKTRİK
        )
    )

当我将其转换为json时，我将workdate元素视为null。

{"workname":"IŞIKLAR MÜHENDİSLİK","workno":"22330","workdate":null}

Answer 1

 $arr = array('workname' => 'IŞIKLAR MÜHENDİSLİK','workno' => 22330,'workdate' => array('0' => array('date' => '','type' => 'ELEKTRİK'),'1' => array('date' => '31.12.2007','type' => 'ELEKTRİK')));

echo json_encode($arr);

输出

{"workname":"I\u015eIKLAR M\u00dcHEND\u0130SL\u0130K","workno":22330,"workdate":[{"date":"","type":"ELEKTR\u0130K"},{"date":"31.12.2007","type":"ELEKTR\u0130K"}]}

    'workdate' => Array (
        Array (

            'type' => 'ELEKTRİK'
       ), 
       Array(
           'date' => '31.12.2007',
           'type' => 'ELEKTRİK'
       )
    )
);    
echo json_encode($arr);
