Adding array into another array (not array_push or array_merge)
Iterate the data subarray, then iterate the sentenceArray, then if the ['path']['type'] value is bus and the ['path']['nodes'] subarray exists, then store that subarray as a separate group in the result array.
Code: (Demo)
$array = json_decode($json, true);foreach ($array['data'] as $datas) { foreach ($datas['sentenceArray'] as $subitem) { if ($subitem['path']['type'] == 'bus' && isset($subitem['path']['nodes'])) { $result[] = $subitem['path']['nodes']; } }}echo json_encode($result);Output:

To filter the results by user-provided value seq:
if (!isset($_GET['seq']) || !ctype_digit($_GET['seq'])){ echo "Missing/Invalid SEQ value.";} else { $array = json_decode($json, true); $result = []; $selected_seq = (int)$_GET['seq']; foreach ($array['data'] as $seq => $datas) { if ($seq === $selected_seq) { foreach ($datas['sentenceArray'] as $subitem) { if ($subitem['path']['type'] == 'bus' && isset($subitem['path']['nodes'])) { $result[] = $subitem['path']['nodes']; } } } } echo json_encode($result);}
Please follow below code:
for($j = 0; $j < $l; $j++) { if($sentenceArray[$j]['path']['type'] == "bus") { $childArr = array(); if(isset($sentenceArray[$j]['path']['nodes'])){ foreach($sentenceArray[$j]['path']['nodes'] as $nodes) { array_push($childArr, $nodes); } } $arrBus[$j] = $childArr; }}$arrBus = array_values($arrBus);$arrBus = json_encode($arrBus);Output as below:
[ [ { "lat":39.952418, "lng":32.85727 }, { "lat":39.952797, "lng":32.856825 }, { "lat":39.953102, "lng":32.856438 } ], [ { "lat":39.964951, "lng":32.841305 }, { "lat":39.964785, "lng":32.841514 } ]]
This code will produce the output that you desire ($json is assumed to contain the JSON from your first snippet):
