如何在php中解析带有数组的JSON字符串

Question

I am sending a JSON string in php post request. JSON string look like this:

{"mobile":"0000000000","otp":"970996", "items":[{"pid":"12", "vid":"20"},{"pid":"13", "vid":"2"}]}

At server side i want to get mobile, otp and pid and vid for all items.

I am getting mobile number from this:

$data = json_decode(file_get_contents('php://input'), true);
//print_r($data);
echo $data["mobile"];

But when i am trying to get pid and vid like this:

foreach($data["items"] as $mydata){

     echo $mydata->pid;
}

i am getting error: Trying to get property of non-object.

How to solve this?

Edit:

If there is any better way to parse JSON in php, please suggest that also.

Answer 1

Just access pid with:

$mydata['pid']

You pass true as a second argument for json_decode

When TRUE, returned objects will be converted into associative arrays.

So you have to treat is as an array, not an object.
