PHP - getting wrong JSON - php

Question

I'm writing a PHP code for inserting the work order name in a spinner.
I need a JSON String called success = 1 along with JSON Array.
I want to use that JSON string in the android spinner.
I'm getting only JSON array.
here is my code:
<?PHP
require_once('connection.php');
$workName = "SELECT workorder_name FROM workorder_category";
$con=mysqli_connect($server_name,$user_name,$password,$db);
$r = mysqli_query($con,$workName);
$result = array();
$resultArr = array('success' => true);
while($row = mysqli_fetch_array($r)){
array_push($result,array('$workOrderName'=>$row['workorder_name']));
}
echo json_encode(array('result'=>$result));
mysqli_close($con);
?>
I want an output as like this:
{"success":1,result":[{"$workOrderName":"electrician"},{"$workOrderName":"plumber"},{"$workOrderName":"carpenter"}]}
currently, I am getting the output like
{
"result": [
{
"$workOrderName": "electrician"
},
{
"$workOrderName": "plumber"
},
{
"$workOrderName": "carpenter"
}
]
}

Answer 1

Instead of creating two arrays, one for the result and one for the success, define the structure in just one array and append to that:
// The main structure
$result = [
'success' => 1,
'result' => [],
];
while($row = mysqli_fetch_array($r)){
// Append to the sub key "result" (which we already defined as an array)
$result['result'][] = ['$workOrderName'=>$row['workorder_name']];
}
// Just encode the complete array
echo json_encode($result);
Note: This example uses the short array syntax [] (introduced in PHP 5.4) instead of the long syntax: array(). They do the exact same thing.
I also changed array_push() to a shorter version: $someArray[] =.

Answer 2

$result = array();
$resultArr['success'] =true;
while($row = mysqli_fetch_array($r))
{
array_push($result,array('$workOrderName'=>$row['workorder_name']));
}
$resultArr['result'] = $result;
echo json_encode($resultArr);
This will work fine.
