Accessing value inside multi-dimension JSON array using PHP

Question

I read several posts on here and have been unable to find success in resolving the problem I am having.

I am trying to figure out how to get the NAME field from the UploadImage array.

I have the following JSON being passed to me from a Webhook.

{
"$version":5,
"Entry":{
    "Number":"11",
    "Order":null,
    "Origin":
        {
        "City":"Portland",
        "CountryCode":"US",
        }
        ,
"Message":"the message",
"UploadImage":[
    {
        "ContentType":"image/png",
        "Id":"F-lMbiCYdwiYS8ppkQS4gsyE",
        "Name":"Screen.png",
        "Size":55907
    }
            ],
"Subject":"here is the subject" 
}

I have no problem grabbing the value of Subject or Message, but I cannot figure out how to grab the NAME within UploadImage.

  $contact = json_decode($json);  
  $subject=$contact->{'Subject'};

When I do

    $uploadimage=$contact->{'UploadImage'};

it just writes out ARRAY.

I can do

 echo  $contact->{'Entry'}->{'Number'};

and it works, so it has to be something with the bracket being there before the curly bracket. I know this has to be something simple that I am missing. Any help is GREATLY appreciated.

Sorry for any confusion. The Entry/Number is not what I need, and it doesn't have the bracket within the array like the UploadImage/Name does. It's the latter that I am trying to retrieve. — Joey Martin

$contact->UploadImage[0]->Name alternatively: $contact = json_decode($json, true); $name = $contact['UploadImage'][0]['Name']; — Brad Kent

Firstly try

$contact = json_decode($json, true);

Adding the second argument returns an array instead of an object which will make things easier. Objects with numerical keys are troublesome... Now you can,

print_r($contact);

to see exactly what you've got. I imagine that

echo $contact['UploadImage'][0]['Name'];

Will get you what you're looking for.

Notice that UploadImage contains an array of objects (or an array of arrays after conversion).

another solution is:

$contact = json_decode($text);
$name = '';
foreach($contact->UploadImage as $k=>$v){
    foreach($v as $k2=>$v2){
        echo $k2.' - '.$v2.'<br />';
        if($k2=='Name'){ $name = $v2;}
    }

};
var_dump($name);

//response

ContentType - image/png
Id - F-lMbiCYdwiYS8ppkQS4gsyE
Name - Screen.png
Size - 55907
//name
string 'Screen.png' (length=10)

Have you try to use like below:

$uploadimage=$contact->UploadImage[0]->Name;

In JSON the square braces [] mark an array section and the curly braces {} mark an object. In your JSON string UploadImage is an array, which contains a single object.

Try changing your JSON as follows:

{
    "$version": 5,
    "Entry": {
        "Number": "11",
        "Order": null,
        "Origin": {
            "City": "Portland",
            "CountryCode": "US"
        },
        "Message": "the message",
        "UploadImage": {
            "ContentType": "image/png",
            "Id": "F-lMbiCYdwiYS8ppkQS4gsyE",
            "Name": "Screen.png",
            "Size": 55907
        },
        "Subject": "here is the subject"
    }
}

If you read the question you'll see that the user is being passed json, probably meaning that the json can't be edited. The question is how to handle the json, not how to format it.
