I am using in my application(its in OSCOMMERCE) , When the user making payment its returning empty response. I debugged and find that it returning this error:

Protocol https not supported or disabled in libcurl

I am sending a prober url starts with https there is no space in that

My application in shared hosting server. My doubt is this is server side problem or Programming problem ?



Create a script called info.php and in it put <?php phpinfo(); ?>. Save it somewhere on your site so you can access it from a browser.

Find the curl section and check what Protocols are supported. If https is not listed, then cURL was not built with SSL support and you cannot use https.

You can also look in the very first section for Registered PHP Streams and see if https is listed. If so, then you can fallback to use PHP's socket functions or functions such as file_get_contents() or fopen with a context.

Since you mention you are on a shared host, request that your host recompile PHP so that both PHP and curl are built with OpenSSL support so you can use encryption, otherwise you will need to find another solution.

Thanks for all the responses, I've ended up with this PHP/cURL-script for caching images (needed by Flash apps to circumvent a missing crossdomain.xml) - seems to work ok with CentOS 5 Linux and php-5.1.6-27.el5:


define('MIN_SIZE', 512);
define('MAX_SIZE', 1024 * 1024);
define('CACHE_DIR', '/var/www/cached_avatars/');

$img = urldecode($_GET['img']);
# img sanity checks omitted here
$cached = CACHE_DIR . md5($img);

if (is_readable($cached)) {
        $finfo  = finfo_open(FILEINFO_MIME);
        $mime   = finfo_file($finfo, $cached);
        $length = filesize($cached);
} else {
        $writefh = fopen($cached, 'wb');
        if ($writefh) {
                flock($writefh, LOCK_EX);
                $ch = curl_init($img);
                curl_setopt($ch, CURLOPT_FILE, $writefh);
                curl_setopt($ch, CURLOPT_HEADER, FALSE);
                curl_setopt($ch, CURLOPT_REFERER, $matches[1]);
                curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
                curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
                curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);

                $error    = curl_errno($ch);
                $length   = curl_getinfo($ch, CURLINFO_SIZE_DOWNLOAD);
                $mime     = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
                $is_image = ($mime != NULL &&
                             (stripos($mime, 'image/gif') !== FALSE ||
                              stripos($mime, 'image/png') !== FALSE ||
                              stripos($mime, 'image/jpg') !== FALSE ||
                              stripos($mime, 'image/jpeg') !== FALSE));

                if ($error || $length < MIN_SIZE || $length > MAX_SIZE || !$is_image) {
                        exit('Download failed: ' . $img);

$readfh = fopen($cached, 'rb');
if ($readfh) {
        header('Content-Type: ' . $mime);
        header('Content-Length: ' . $length);

        flock($readfh, LOCK_SH);

        while (!feof($readfh)) {
                $buf = fread($readfh, 8192);
                echo $buf;

This was a bug in curl and fixed on 7.28.1 (according to this page

Note: Modern browsers doesnt send fragment part at the request. But your curl sending it, this is making difference.

Probably not what you want to hear, but they have known issues at the moment with ARM.

This workaround seems to work for me:

  • Directly download rustup-init from for your platform
  • env RUSTUP_USE_HYPER=1 ./rustup-init

It should also work to export RUSTUP_USE_HYPER=1 (assuming you aren't using tcsh) before running the rustup script, but the above is what I tested and used.

So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

"The file is being created by user oracle just noticed this in our development database. i'm getting this error because, the directory where i try to create the file doesn't have write access for others and user oracle comes under others category. "

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN(). Find it here.

P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.
