Hello, I have an array that I want to transfer it into another format. The array look like: $data = [ [ "id"=>1, "type"=>"title", "data"=> "Title goes here" ], [ "id"=>2, "type"=>"repeat", "number"=>3, ], [ "id"=>3, "type"=>"media", "data"=> "path to media" ], [ "id"=>4, "type"=>"close_repeat" ], [ "id"=>5, "type"=>"repeat", "number"=>3, ], [ "id"=>6, "type"=>"title", "data"=> "Title goes here" ], [ "id"=>7, "type"=>"repeat", "number"=>2, ], [ "id"=>8, "type"=>"text", "data"=> "Text goes here" ], [ "id"=>9, "type"=>"close_repeat" ], [ "id"=>10, "type"=>"close_repeat" ], [ "id"=>11, "type"=>"cover", "data"=> "Cover data goes here" ], ]; And I want to transform it into: { "0": [ { "id": 1, "type": "title", "data": "Title goes here" } ], "1": [ { "id": 3, "type": "media", "data": "path to media" }, { "id": 3, "type": "media", "data": "path to media" }, { "id": 3, "type": "media", "data": "path to media" } ], "2":[ { "id": 6, "type": "title", "data": "Title goes here" }, { "id": 8, "type": "text", "data": "Text goes here" }, { "id": 8, "type": "text", "data": "Text goes here" } ], "3":[ { "id": 6, "type": "title", "data": "Title goes here" }, { "id": 8, "type": "text", "data": "Text goes here" }, { "id": 8, "type": "text", "data": "Text goes here" } ], "4":[ { "id": 6, "type": "title", "data": "Title goes here" }, { "id": 8, "type": "text", "data": "Text goes here" }, { "id": 8, "type": "text", "data": "Text goes here" } ], "5": [ { "id": 11, "type": "cover", "data": "Cover data goes here" } ] } The idea is that each object can appear once or multiple times. If an object comes between objects of type repeat and close_repeat then it should be repeated based on number:x. The problem is when the repeat is nested as in id=5 to id=10. Here it should be that id=6 appear once with two repeated id=8. But in total, this whole id=6 and id=8 (twice) should appear three times since the repetition at id=5 is 3. I hope this is clear. I tried using loops: public function dataTraversLoop($data, &$newData, $i){ $dataCount = count($data); if($i>=$dataCount){ return; } $objectIndex=0; for(;$i<$dataCount;$i++){ if($data[$i]['type']=='repeat'){ $objectIndex++; $repeat = $data[$i]['number']; $i++; for($j=0;$j<$repeat;$j++){ $tmpData = $data[$i]; $newData [$objectIndex][$j] = $tmpData; } } else if($data[$i]['type']=='close_repeat'){ $i++; $objectIndex++; } else{ $tmpData = $data[$i]; $newData [$objectIndex][] = $tmpData; } } } And also recursion: public function dataTravers($data, &$newData, &$repeat, $i, $objectIndex){ $dataCount = count($data); for( ; $i<$dataCount; $i++){ if($data[$i]['type']=='repeat'){ $repeat = $repeat * $data[$i]['number']; return $this->dataTravers($data, $newData, $repeat, $i+1, $objectIndex); } if($data[$i]['type']=='close_repeat'){ $repeat = 1; return $this->dataTravers($data, $newData, $repeat, $i+1, $objectIndex+1); } if($i >= $dataCount){ return $newData; } $tmpData = $data[$i]; $newData [$objectIndex][] = $tmpData; return $this->dataTravers($data, $newData, $repeat, $i+1, $objectIndex); $objectIndex++; }
