curl_exec always returns 0?

Question

I have this function:

function Connect($url, $post = 0, $postfields = '') 
{
    $ch = curl_init();
    if($post > 0) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
    } 
    curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__).'/joomla-cookie.txt');
    curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__).'/joomla-cookie.txt');
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    $exec = curl_exec($ch);
    if($exec) { return $exec; } else { return 0; }
}

I call it like that Connect($host)

And it always return 0...

`$host` suggests you are sending "google.com" , where as the url needed is `http://google.com`, what are you using? — Sabeen Malik, Jun 08 '11 at 22:57
@Sabeen i acctually sending it with the https:// Maybe it's cuz https:// and not http:// ? cuz "http://www.google.com" works. — Danpe, Jun 08 '11 at 23:05

Try setting CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST to false. that should do the trick.

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

@Sabeen There is a way to enable the cookie to support SSL too? Cuz the session only saves when im using http:// ... – Danpe Jun 08 '11 at 23:27
I don't think the https should effect the way cookies are stored. Look at the joomla-cookie.txt file to see what it contains, that might give u some clues. – Sabeen Malik Jun 08 '11 at 23:38
@Sabeen Yup i dont think it should effect it also, but it does lol. I have no clue in cookies.. Here is the pastebin: http://pastebin.com/RX9vnEbT – Danpe Jun 08 '11 at 23:41

Are you moving between http and https? – Sabeen Malik Jun 08 '11 at 23:41
@Sabeen I think so, not sure though. – Danpe Jun 08 '11 at 23:42

try to make sure that you start with https and submit to https. I believe if you will cross over between https and http, you will loose the cookie. Also is the domain the same for https as well. sometimes sites have https://secure.domain.com etc – Sabeen Malik Jun 08 '11 at 23:44
Please note that [disabling VERIFYPEER or VERIFYHOST makes the connection vulnerable to MITM attacks](http://stackoverflow.com/a/13742121/372643). – Bruno Nov 21 '14 at 11:27

Check if there was an error with the request after curl_exec:

if(curl_errno($ch)){
    echo 'Curl error: ' . curl_error($ch);
}

That will provide you with enough info to know if there was a error with the request. If there was no error, you can check the request sent after curl_exec so you can double check that everything sent is in place:

print_r(curl_getinfo($ch));
