Why I can't format my JSON object? - php

Question

I'm trying to construct a json object containing inner objects.
I'm trying the following code - where $ids is an array containing some IDs:
$result = array();
foreach ($ids as $value) {
$tempArray = getCustomOptions($host, $dbUsername, $dbPassword, $dbName, $_SESSION['companyId'], $value);
array_push($result, $tempArray);
}
print_r(json_encode($result));
The getCustomOptions() also returns an array using the following script:
$dataArray = [];
while ($stmt->fetch()) {
$dataArray[] = array(
'id' => $id,
'description' => $description
);
}
The problem is that when I print_r(json_encode($result)); I'm getting the following result:
[
[
{
"id":21,
"description":"Bshd"
},
{
"id":22,
"description":"Gandhi "
},
{
"id":23,
"description":"aaaa"
},
{
"id":24,
"description":"bbbbb"
}
],
[
{
"id":12,
"description":"121"
},
{
"id":13,
"description":"qwe"
},
{
"id":16,
"description":"wD2"
},
{
"id":17,
"description":"we"
}
],
[
]
]
As you can see it returns some arrays inside of an array, but what I really need is the following structure:
{
"data1":[
{
"id":21,
"description":"Bshd"
},
{
"id":22,
"description":"Gandhi "
},
{
"id":23,
"description":"aaaa"
},
{
"id":24,
"description":"bbbbb"
}
],
"data2":[
{
"id":12,
"description":"121"
},
{
"id":13,
"description":"qwe"
},
{
"id":16,
"description":"wD2"
},
{
"id":17,
"description":"we"
}
]
}
I know that I'm missing something really small and basic here, but for me the JSON manipulation in php is still hard.
Can somebody give me a clue or a push?

Answer 1

you can try following code to generate your array in a proper format.
$result = array();
$i=1;
foreach ($ids as $value) {
$tempArray = getCustomOptions($host, $dbUsername, $dbPassword, $dbName, $_SESSION['companyId'], $value);
$result['data'.$i] = $tempArray;
$i++;
}

Answer 2

Don't use array_push() that just creates a normal array element. Use $array_variable[$key] = ... to assign values to a specific associative array key.
