Printing a foreach loop in a loop maintaining json - php

Question

I have this code as I am trying to implement a json code using foreach loop
foreach ($single_google as $row) {
$data['step'][] = array(
"#type" => "HowToStep",
"url" => "https://example.com/kitchen#step1",
"name" => "Prepare the surfaces",
"itemListElement" => array(),
"image" => [
"#type" => "ImageObject",
"url" => "https://example.com/photos/1x1/photo-step1.jpg",
"height" => "406",
"width" => "305"
],
);
$all_step_google = json_decode($row["steps"]);
foreach ($all_step_google as $single_step_google) {
$data['itemListElement'][] = array(
"#type" => "HowToDirection",
"text" => "testing",
);
}
}
print_r(json_encode($data));
at the end of the coding, trying to run it I got this
{
"#type": "HowToStep",
"url": "https://example.com/kitchen#step1",
"name": "Prepare the surfaces",
"itemListElement": [],
"image": {
"#type": "ImageObject",
"url": "https://example.com/photos/1x1/photo-step1.jpg",
"height": "406",
"width": "305"
}
}
],
"itemListElement": [
{
"#type": "HowToDirection",
"text": "test."
}
instead of this which I needed actually.
{
"#type": "HowToStep",
"url": "https://example.com/kitchen#step1",
"name": "Prepare the surfaces",
"itemListElement": [
{
"#type": "HowToDirection",
"text": "Test"
}
],
"image": {
"#type": "ImageObject",
"url": "https://example.com/photos/1x1/photo-step1.jpg",
"height": "406",
"width": "305"
}
}
],
I want the "itemListElement" => array(), to print before the "image" => [] but it kept printing after the foreach loop. Please help me, am getting lost.

Answer 1

You use $data['itemListElement'][] = array(... on your second loop so that will assign new key to your data master array instead, the right code should be like this
............
foreach ($all_step_google as $key => $single_step_google) {
$data['step'][$key]['itemListElement'][] = array(
"#type" => "HowToDirection",
"text" => "testing",
);
}
............
