php curl with CURLOPT_FOLLOWLOCATION error

Question

i got an error

CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in

i google many solution, but with this site they don't work. only need CURLOPT_FOLLOWLOCATION. stupid hoster don't want to enable safe_mode or an open_basedir . can i enable them by myself, may be create htaccess with some parameters?

Answer 1

The error means safe_mode or open_basedir ARE enabled (probably open_basedir) you probably can't override either if your host has any decent security settings.

So you have a choice

1) change host (not really desirable I imagine)

2) use a function similar to ones found on the php curl_setopt page, i.e. http://www.php.net/manual/en/function.curl-setopt.php#95027

The following is a fixed version of the function specified in point 2

function curl_redirect_exec($ch, &$redirects, $curlopt_header = false) {
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $data = curl_exec($ch);

    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if ($http_code == 301 || $http_code == 302) {
        list($header) = explode("\r\n\r\n", $data, 2);

        $matches = array();
        preg_match("/(Location:|URI:)[^(\n)]*/", $header, $matches);
        $url = trim(str_replace($matches[1], "", $matches[0]));

        $url_parsed = parse_url($url);
        if (isset($url_parsed)) {
            curl_setopt($ch, CURLOPT_URL, $url);
            $redirects++;
            return curl_redirect_exec($ch, $redirects, $curlopt_header);
        }
    }

    if ($curlopt_header) {
        return $data;
    } else {
        list(, $body) = explode("\r\n\r\n", $data, 2);
        return $body;
    }
}

Answer 2

If you specify that only http and https protocols are allowed during redirect using CURLOPT_REDIR_PROTOCOLS, you would be able to use CURLOPT_FOLLOWLOCATION without safe_mode or open_basedir.
