Create nested JSON with dynamic keys with PHP - php

Question

I get some data from an API call and I try to construct a JSON to send it back to another API.
The final JSON must look like this:
{
"jobs": {
"MP_OFFER_ID_1": {
"job_id": "jobboard_reference_1",
"url": "url_1",
"status": 0
},
"MP_OFFER_ID_2": {
"job_id": "job_id_2",
"url": "url_2",
"status": 1
},
}
}
So under the jobs key, it's not an array of elements but a list of elements with unique keys.
And that's what I'm having trouble to get.
The data I want to parse is in an array structured like this:
Array(
[0] => Array(
[link] => some-url
[id] => 18790674
[ref] => 0015909-18790674
)
// ...
);
link has to be placed in the url key of the JSON.
id is the JSON key, in the examples it's MP_OFFER_ID_1 etc
ref has to be placed in job_id
I actually have this JSON at the end:
{
"jobs": [
[
{
"18790674": {
"job_id": "0015909-18790674",
"url": "test",
"status": 1
}
},
{
"18790678": {
"job_id": "0015892-18790678",
"url": "test",
"status": 1
}
}
]
]
}
As you can see, jobs is an array (actually it's an array of array ^^) and that's not what I want here...

I came up with this, but it was very difficult to understand what exactly you want from the very limited info in question:
<?php
$input = [
[
'id' => 18790674,
'link' => 'some-url',
'ref' => '0015909-18790674',
],
[
'id' => 18790678,
'link' => 'another-url',
'ref' => '0015909-18790678',
],
];
$output = new stdClass();
foreach ($input as $arr) {
$obj = new stdClass();
$key = $arr['id'];
$obj->job_id = $arr['id'];
$obj->url = $arr['link'];
$obj->status = '1'; // ?
$output->{$key} = $obj;
}
echo json_encode($output, JSON_PRETTY_PRINT);
Output:
{
"18790674": {
"job_id": 18790674,
"url": "some-url",
"status": "1"
},
"18790678": {
"job_id": 18790678,
"url": "another-url",
"status": "1"
}
}
