如何从php解码？

 $object_from_json = json_decode('{"user_id":1,"itemList":[{"max_price":120,"min_price":100,"trend":"high","c_price":110,"status":"1","type":"veg","item_id":19},{"max_price":200,"min_price":100,"trend":"low","c_price":100,"status":"1","type":"veg","item_id":224}],"table_no":"1"}');

//or

$array_from_json = json_decode('{"user_id":1,"itemList":[{"max_price":120,"min_price":100,"trend":"high","c_price":110,"status":"1","type":"veg","item_id":19},{"max_price":200,"min_price":100,"trend":"low","c_price":100,"status":"1","type":"veg","item_id":224}],"table_no":"1"}', true);
//then you got a Array in PHP
//var_dump($array_from_json);

//with an URL 
$array_from_json_url = json_decode(file_get_contents($json_url), true);
//var_dump($array_from_json_url);

你需要在你的页面上PHP orderDetails.php添加响应头，需要在echo之前是一个json格式

header("Content-type:application/json");
//$output is array or object PHP
echo json_encode($oupout);

如何解码json以获取我的网址中的json数据？
