PHP curl and getting HTTPS site's html source code - php

Question

I wrote this code for getting https pages content but i couldnt succesfull.
<?php
function bot($url)
{
$header ="Host: tr-tr.facebook.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0\r\n
Accept: */*
Accept-Language: tr-TR,tr;q=0.8,en-US;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate, br";
$options = array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_PORT => 443,
CURLOPT_SSL_VERIFYPEER => true,
CURLOPT_SSL_VERIFYHOST => 2,
CURLOPT_CAINFO => "C:\\xampp\\htdocs\\curl-ca-bundle.crt",
CURLOPT_HTTPHEADER => explode("\r\n",$header)
);
$ch = curl_init();
curl_setopt_array($ch, $options);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
echo bot("https://tr-tr.facebook.com");
?>
When i run that codes it is returning that. "��0#a�jȌ#�#.3�j�##u�.����/#cw#,�q=ߓ���K"<�˞#%#����t[�d�:|��s##$!� ��(��M��ߛ#w'#u" Where is my mistake? Why is returning these characters?
I dont want to use CURLOPT_SSL_VERIFYPEER = false. I want to https handshake with curl..

Answer 1

Maybe you should remove CURLOPT_RETURNTRANSFER or handle it properly.
From the manual
http://php.net/manual/en/function.curl-setopt.php
Do you really want this?!
> CURLOPT_RETURNTRANSFER
> TRUE to return the transfer as a string of the
> return value of curl_exec() instead of outputting it out directly.
