Why does the Cloudflare stub drop out when parsing?

Question

PHP

It was necessary to pull off the headers from the site, but instead of content, parsing on KURL gets Clara's stub

. Although when you open it with a browser, everything opens without it.
Curl code that should open the page

$url=$_GET['url'];

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31');
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, '1');
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 20);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$text = curl_exec($ch);

How to bypass it?

Answer 1

There is a python library - Cloudflare-scraper
https://github.com/Anorov/cloudflare-scrape
Works great with Cloudflare protection.
Perhaps there is something similar in php ...

Answer 2

imitate a complete browser, store cookies and pass them on connection
