如何用php输出这种json格式

{"0":{"lid":"1","title":"1"},"1":{"lid":"2","title":"2"}}

Answer 1

$arr1 = array('title'=>1,'id'=>2);
$arr1 = json_encode($arr1);
print_r($arr1);

打印这样的，{"title":1,"id":2}，之后的自己想

Answer 2

json_encode(array('0'=>array('lid'=>'1','title'=>'1'),'1'=>array('lid'=>'2','title'=>'2')),JSON_FORCE_OBJECT);

Answer 3

如果json_encode不能满足，就自己写串拼吧，这是程序员最喜欢做的事了

Answer 4

$arr = array('0'=>array('id'=>'11', 'title'=>112), '2'=>array('id'=>33, 'title'=>44));
echo json_encode($arr);

Answer 5

json_encode
json_decode
