PHP cURL SSL Connect Error

Question

I have tried to display content of SSL webpage using file_get_contents() function.

$url = base64_decode("aHR0cHM6Ly93d3cudGVudGtvdHRhLmNvbQ==");
echo file_get_contents($url);

$header = array("Connection: Keep-Alive", "User-Agent: Mozilla/5.0");
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, $header);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 3600);
curl_setopt($ch, CURLOPT_SSLVERSION , 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);     
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
$result = curl_exec($ch);
if($errno = curl_errno($ch)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
}
curl_close($ch);
echo $result;

But it throws me a warning says,

Warning: file_get_contents(): Failed to enable crypto in

Then I tried to get using cURL library. But it also gives me an error no 35 which is SSL Connect Error.

I have searched on cURL site and it says error while connecting webpage.

CURLE_SSL_CONNECT_ERROR (35)

A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.

could you please anyone help me with this.

Thank you.

TLDR:

I fixed up your code. Here is a working example:

$url = base64_decode("aHR0cHM6Ly93d3cudGVudGtvdHRhLmNvbQ==");

$header = array("User-Agent: Mozilla/5.0");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);
if($errno = curl_errno($ch)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
}
curl_close($ch);
echo $result;

A Longer Explanation

After base64 decoding $url is equal to https://www.tentkotta.com which (when requested with the code in your question) returns an HTTP 500 Internal Server Error:

            <a href="javascript:history.back();" title="Back">Back</a>
            </div>
            </div>

        </div>
    </div>
</div>
</div>

To stop causing errors on the server side, you need to change this line:

curl_setopt($ch, CURLOPT_HEADER, $header);

to

curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

CURLOPT_HEADER is for response headers. CURLOPT_HTTPHEADER is for request headers. See the curl_setopt docs for details.

Also, remove this line:

curl_setopt($ch, CURLOPT_SSLVERSION , 3);

SSLv3 has likely been disabled on your target URL due to the POODLE vulnerability. Just let cURL and the host negotiate the best protocol instead of specifying it yourself.

Additionally, the following lines are not necessary since https://www.tentkotta.com does appear to have a valid SSL Certificate:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

Also, if you want the $result variable to contain the response body of the HTTP request, you should add this line:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

Beyond that many of your other settings such as "Connection: Keep-Alive", CURLOPT_TIMEOUT and CURLOPT_IPRESOLVE aren't helping in this example and can safely be removed.

thank you for your time. Site is completely working on web browser. I would like to display the contents. I'm not owner of the site. I cannot modify it from server. How could I be able to display in result?

Asaph Over a year ago

I included a working example at the top of my answer. Please try it.

CyberHelp Over a year ago

it gave me same error "cURL error (35): SSL connect error" on my localhost MAMP

Asaph Over a year ago

cURL error (35): SSL connect error is caused by this line: curl_setopt($ch, CURLOPT_SSLVERSION , 3);. If you're getting that error, you must not be running my example code which doesn't include that line.

CyberHelp Over a year ago

I'm running your example. I just copy and paste it and checked.
