It is necessary that in the detailed description it goes something like this: You can buy this product at a price of.... rub.
Help plz!

Answer 1

In the detailed description, write text text text ... You can buy this product at the price of #PRICE_1# rub. .... text text text
#PRICE_1# is a macro, in which 1 is the ID of the desired price type (here, if desired, a symbolic price code can also be used)
If on the example of simple goods, the code looks something like this

if($arResult['DETAIL_TEXT']) {
  $arPrices = $aSearch = $aReplace = array();

  preg_match_all('/#PRICE_\d#/', $arResult['DETAIL_TEXT'], $matches);
  
  if($matches[0]) {
    $iterator = \Bitrix\Catalog\PriceTable::getList([
      'select' => ['CATALOG_GROUP_ID', 'PRICE', 'CURRENCY'],
      'filter' => ['PRODUCT_ID' => $arResult['ID']]
    ]);

    while($row = $iterator->fetch()) {
      $arPrices[$row['CATALOG_GROUP_ID']] = CCurrencyLang::CurrencyFormat($row['PRICE'], $row['CURRENCY']);
    }
    
    $aSearch = $matches[0];
    
    foreach($aSearch as $key => $str) {
      $priceId = str_replace(['#', 'PRICE_'], '', $str);
      $aReplace[$key] = $arPrices[$priceId];
    }
    
    $arResult['DETAIL_TEXT'] = str_replace($aSearch, $aReplace, $arResult['DETAIL_TEXT']);
  }
}
