Why does the script from under the crown in Bitrix not work?
It does not work when I write this in the file before the script code
<?php
$_SERVER["DOCUMENT_ROOT"] = "/home/c/cok23/caytex.ru/public_html";
$DOCUMENT_ROOT = $_SERVER["DOCUMENT_ROOT"];
define("NO_KEEP_STATISTIC", true);
define("NOT_CHECK_PERMISSIONS", true);
define("BX_CRONTAB", true);
//set_time_limit(0);
define("LANG", "en");
define('CHK_EVENT', true);
set_time_limit(0);
ignore_user_abort(true); ?>
<? require($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_before.php");?>

<? require($_SERVER["DOCUMENT_ROOT"]."/ bitrix /modules/main/include/prolog_before.php");?>
Without all this, everything works

does not work

Answer 1

Try to use the full syntax to open the PHP code: <?php
So the last line should look like this:

<? require($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_before.php");?>

The short syntax (only brace and question angles) is deprecated and depricated. It may work depending on the PHP settings on the hosting (adjusted by setting short_open_tag=On), but it's best to avoid it. The modern approach is to write in full: <?phpor<?=
