Remove JSON Block with PHP - php

Question

I have two JSON Files which I merge with a PHP Script. My PHP script looks like this:
<?php
header('Content-Type: application/json');
$a = file_get_contents("https://example.com/a.json", false);
$b = file_get_contents("https://example.com/b.json", false);
$merge = json_encode(array_merge(
json_decode($a, true),
json_decode($b, true)
));
echo $merge;
?>
My Output looks like this:
[{
"id": 1141,
"iid": 167,
"project_id": 17,
"title": "test",
"description": "test",
"state": "opened",

}
}]
Now I want to remove each block with "project_id": 16. How can i remove every Block with "project_id": 16?
So i would like to remove this Block. And everyone else with "project_id": 16, if there were any more.
{
"id": 1140,
"iid": 166,
"project_id": 16,
"title": "test2",
"description": "test2",
"state": "opened",
"created_at": "2018-02-19T11:01:00.729Z",
"updated_at": "2018-02-19T11:01:00.729Z",
"closed_at": null,
"labels": [],
"milestone": null,
"assignees": [{
"id": 5,
"state": "active"
}],
"author": {
"id": 5,
"state": "active"
},
"assignee": {
"id": 5,
"state": "active"
},
"user_notes_count": 0,
"upvotes": 0,
"downvotes": 0,
"due_date": null,
"confidential": false,
"discussion_locked": null,
"time_stats": {
"time_estimate": 0,
"total_time_spent": 0,
"human_time_estimate": null,
"human_total_time_spent": null
}
},
I'm grateful for any help.

Here a little snippet
$merge = array_filter($merge, function($item){ return $item['project_id'] != 16 })
