safe_mode i

Answer 1

Never tested in real environment but has more transparency with curl_exec (no problem with header and returntransfer options).

function curl_exec_follow(/*resource*/ $ch, /*int*/ $maxredirect = 5) {
    if (ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off')) {
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    } else {
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
        $newurl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

        $rch = curl_copy_handle($ch);
        curl_setopt($rch, CURLOPT_HEADER, true);
        curl_setopt($rch, CURLOPT_NOBODY, true);
        curl_setopt($rch, CURLOPT_RETURNTRANSFER, true);
        do {
            curl_setopt($rch, CURLOPT_URL, $newurl);
            $header = curl_exec($rch);
            if (curl_errno($rch)) {
                $code = 0;
            } else {
                $code = curl_getinfo($rch, CURLINFO_HTTP_CODE);
                if ($code == 301 || $code == 302) {
                    preg_match('/Location:(.*?)\n/', $header, $matches);
                    $newurl = trim(array_pop($matches));
                } else {
                    $code = 0;
                }
            }
        } while ($code && $maxredirect--);
        curl_close($rch);
        curl_setopt($ch, CURLOPT_URL, $newurl);
    }
    return curl_exec($ch);
}
