Tell me, please, what should be the regular expression in order to parse from the page everything that is between and I, alas, still cannot comprehend these regular expressions :(

<div id="programm_up">

$link = "http://www.teleguide.info/kanal100055_20160413.html";

<?php
  $link = "http://www.teleguide.info/kanal100055_20160413.html";
  $page = file_get_contents($link);
  $regExpWrapper = "#(?:<div id=\"programm\">)(.*?)(?:<div id=\"programm_up\">)#si";
  preg_match_all($regExpWrapper, $page, $matches);
  echo iconv("UTF-8", "CP1251", $matches[1][0]);
?>
