How to create json array php with childs - php

Question

i am struggling with encoding json data
when posting to confluenec it needs to be
{"id":"282072112","type":"page","title":"new page","space":{"key":"BLA"},"body":{"storage":{"value":"<p>This is the updated text for the new page</p>","representation":"storage"}},"version":{"number":2}}'
so in php i created
$data = array('id'=>$siteid, 'type'=>'page', 'title'=>'title of the page');
$data_json = json_encode($data);
print_r ($data_json);
The endresult should look like
{
"id": "282072112",
"type": "page",
"title": "new page",
"space": {
"key": "BLA"
},
"body": {
"storage": {
"value": "<p>This is the updated text for the new page</p>",
"representation": "storage"
}
},
"version": {
"number": 2
}
}
but how can i add the childs etc?
Thanks

Answer 1

You can nest data in arrays similarly to what you would to in JavaScript:
$data = [
'id' => $siteid,
'type' => 'page',
'title' => 'new page',
'space' => [
'key' => 'BLA',
],
'body' => [
'storage' => [
'value' => '<p>...</p>',
'representation' => 'storage'
],
],
'version' => [
'number' => 2,
],
];
// as JSON in one line:
echo json_encode($data);
// or pretty printed:
echo json_encode($data, JSON_PRETTY_PRINT);

Answer 2

$data = [
"id" => $siteid,
"type" => "page",
"space" => ["key" => "bla"]
//...
]
You can nest arrays.

Answer 3

Try it
$data_child = array( 'value'=> 'blablabla' );
$data = array('id'=>$siteid, 'type'=>'page', 'title'=>'title of the page', 'child' => $data_child );
$data_json = json_encode($data);

Answer 4

You can create nested array this way and the send it after json_encode()
<?php
$preparing_array = array
(
"id" => 282072112,
"type" => "page",
"title" => "new page",
"space" => array
(
"key" => "BLA"
),
"body" => array
(
"storage" => array
(
"value" => "<p>This is the updated text for the new page</p>",
"representation" => "storage"
)
),
"version" => array
(
"number" => 2
)
);
echo json_encode($preparing_array, JSON_PRETTY_PRINT);
?>
