Question

1C-Bitrix

I can’t convert to json, I try, but it didn’t work json_encode($prop, JSON_FORCE_OBJECT);

$prop = Array
(
    [0] => Array
        (
            [NAME] => ИДН 500 - средний элемент
            [PREVIEW_PICTURE] => /upload/iblock/501/IDN_500_S_2.jpg
            [PRICE] => 1575.00
        )

    [1] => Array
        (
            [NAME] => ИДН 500 - концевой элемент
            [PREVIEW_PICTURE] => /upload/iblock/c2c/IDN_500_K_2.jpg
            [PRICE] => 788.00
        )

)

<? require_once($_SERVER['DOCUMENT_ROOT'].'/bitrix/modules/main/include/prolog_before.php');

if(!CModule::IncludeModule("iblock"))
return; 

$idarr = $_POST;
$prop = array();
$count = 0;
foreach ($_POST as $id){
    $res = CIBlockElement::GetByID(+$id);
    
    if($ar_res = $res->GetNext()) {
       
        $prop[$count]['NAME'] = $ar_res['NAME'];
        $prop[$count]['PREVIEW_PICTURE'] = CFile::GetPath($ar_res['PREVIEW_PICTURE']);
        $prop[$count]['PRICE'] = CPrice::GetBasePrice($ar_res['ID'])['PRICE'];
      
    }
    $count++;

}

echo \Bitrix\Main\Web\Json::encode($prop);


?>
