Question

PHP

I'm trying to get data from an ajax request via curl, tell me what I'm doing wrong

$url = "https://razmerkoles.ru/size/bmw/x6/2018";

function getCurlResult ($url) {
  global $arrProxy;
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLPROTO_HTTPS,1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); 
  curl_setopt($ch, CURLOPT_PROXY, "103.239.54.56:45462");
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);// таймаут в секундах
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/17.17134');
  curl_setopt($ch, CURLOPT_VERBOSE, true);
  curl_setopt($ch, CURLOPT_COOKIEJAR, "C:\Users\vova_\AppData\Local\Google\Chrome\User Data\Default\Cookies");
  curl_setopt($ch, CURLOPT_COOKIEFILE, "C:\Users\vova_\AppData\Local\Google\Chrome\User Data\Default\Cookies");
  $htmltext = curl_exec($ch);
  curl_close($ch);	
  //$htmltext = iconv("CP1251", "UTF-8", $htmltext);
  return $htmltext;
}
  
$zz = 0;

$html = getCurlResult($url);

$startpos = strpos($html, 'sRwd=\'');// достаю значения атрибута data-rim и data-front
$curlStrCopy = $html;
$startpos +=strlen('sRwd=\'');
$html = substr($html, $startpos);
$endPos = strpos($html, '\';');
$str = substr($curlStrCopy, $startpos, $endPos);
// echo $zz++;
echo "<pre>";
echo $str . "<br>";
echo "</pre>"; 

$url_site = "https://razmerkoles.ru";

$curl_code = getCurlResult($url_site . $str);
