How can I push an object outside a function? - php

Question

I need to write an API that have all the table column but with the option of skipping the nullable field/column.
somehow the array return empty, can you figured out what happen?
store function ==>
public function store(Request $request)
{
$dataTable = [];
function checkifexist($column,$request_name,$request,$dataTable){
if($request->has($request_name)){
addData($column,$request_name,$dataTable);
}
}
function addData($column,$request_name,$request,$dataTable){
// $dataTable[$column] = $request[$request_name];
array_push($dataTable,array($column => $request[$request_name]));
}
try {
addData("example_field","example_field",$request,$dataTable); //required
checkifexist("example_number_two","example_number_two",$request,$dataTable);
//check if the request have this option
item::create($dataTable);
$data["success"] = true;
$data["code"] = 200;
$data["message"] = "success";
$data["data"] = ["this is the data you are inputing"=>$dataTable];
} catch (\Throwable $th) {
$data["data"] = [];
$data["success"] = false;
$data["code"] = 500;
$data["message"] = $th->getMessage();
}
return $data;
}
postman request ==>
method = "post";
body:{
example_field:"value"
}
result of postman ==>
{
"success": true,
"code": 200,
"message": "success",
"data": {
"this is the data you are inputing": []
}
}

$dataTable = [];
function addData($column,$request_name,$request,$dataTable){
$dataTable[$column] = $request[$request_name];
return $dataTable;
}
function checkifexist($column,$request_name,$request,$dataTable){
if($request->has($request_name)){
$newData = addData($column,$request_name,$request,$dataTable);
return $newData;
}
}
$dataTable = addData("item_id","item_id",$request,$dataTable);
$dataTable = checkifexist("name","name",$request,$dataTable);
postman result ==>
{
"success": true,
"code": 200,
"message": "success",
"data": {
"this is the data you are inputing": {
"ExampleField": "1",
"ExampleFiledTwo": "sdsad"
}
}
