hey i'm trying curl "https://www.libertyreserve.com/captcha.jpg"
tried curl result "1x1" gif pic
reialized site want cookie login page show valid captcha used function

$file['cookie'] = "cookie.txt"; function curl_page($url='',$var=''){     global $file;     $curl = curl_init();     curl_setopt($curl, curlopt_url, $url);     curl_setopt($curl, curlopt_connecttimeout,20);     curl_setopt($curl, curlopt_useragent, 'mozilla/5.0 (windows nt 6.2; wow64) applewebkit/537.31 (khtml, gecko) chrome/26.0.1410.64 safari/537.31');     curl_setopt($curl, curlopt_referer, "http://www.libertyreserve.com/en/login");     curl_setopt($curl, curlopt_followlocation, true);     if($var) {     curl_setopt($curl, curlopt_post, 1);     curl_setopt($curl, curlopt_postfields, $var);     }     curl_setopt($curl, curlopt_cookie,$file['cookie']);     curl_setopt($curl, curlopt_cookiefile,$file['cookie']);     curl_setopt($curl, curlopt_cookiejar,$file['cookie']);     curl_setopt($curl, curlopt_ssl_verifyhost, 3);     curl_setopt($curl, curlopt_header, 0);     curl_setopt($curl, curlopt_returntransfer, true);     curl_setopt($curl, curlopt_ssl_verifypeer, false);     $result = curl_exec($curl);     curl_close($curl);     return $result; } 

then curl login page

$loginpage = curl_page("https://www.libertyreserve.com/en/login"); 

then curl pic , put header , print

$imagecode = curl_page("https://www.libertyreserve.com/captcha.jpg"); header("content-type: image/gif"); echo $imagecode; 

but result still "1x1" bcz curl function don;t save cookies
p.s : site response "content-type: image/gif" put in header

few observation

• you not sharing cookie cause don't need curlopt_cookie
• even if ssl verification false .. need add certification information see code not work without disabling ssl on how can done

here working code:

$ch = new sharedcurl(__dir__ . "\libertyreserve.crt");  try {     $ch->get('https://www.libertyreserve.com/en/login');     $image = $ch->get('https://www.libertyreserve.com/captcha.jpg');     header("content-type: image/gif");     echo $image; } catch (exception $e) {     print $e->getmessage(); } 

output
