How to make contents of php nested array json objects within an outer array using json_encode

Question

I have an array:

$myAssocArray = array(
           ['fred','tyson',23],
           ['collins', 'white', 54],
           ['mary', 'frost', 46]
        );

When I json_encode the array:

$jsonString = json_encode($myAssocArray);
echo $jsonString;

I get:

[['fred','tyson',23],['collins', 'white', 54],['mary', 'frost', 46]]

But I would like the following result:

[{0:'fred',1:'tyson',2: 23},{0:'collins', 1:'white', 2: 54},{0:'mary', 1:'frost',2: 46}]

You can pass JSON_FORCE_OBJECT to the second argument of json_encode but that will not result in the exact value that you want. — Spoody

Hi, I think that this means nothing in JSON "[{'fred','tyson',23},{'collins', 'white', 54},{'mary', 'frost', 46}]". — Jubei

(a) Your PHP isn't an associative array, it's just an array of arrays. (b) The output you're showing is also an array of arrays, so it makes sense. (c) Your expected output isn't valid JSON. It's impossible to get that output from json_encode(). — Chris

It seems to have worked after I cast the sub arrays to objects — Winnipass

Found a solutiion, I had to cast the nested array to objects

(object) $myDynamicNestedArray;

PHP json_encode - JSON_FORCE_OBJECT mixed object and array output

Chris I understand the output i typed in the quesstion is not valid json (I was just free styling on the keyboard not checking syntax), but the problem is still valid if you change it to a valid json string

I just edited the final json output in the question. With regards to the answer. $dataArray->push((object)$data->all()); $dataArray->toJson(); ended up giving me the output I was expecting

Convert the array to an object (object)$array, something like:

function _json_encode($arr){
   return json_encode((object)$arr); 
}

$jsonString = _json_encode($myAssocArray);
print_r($jsonString);
