There may be certain servers which do not allow curl options so there is a alternate option for it. We can use the following code instead of curl:

$file = fopen ($url, "r");
if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
}
while (!feof ($file)) {
 $line = fgets ($file, 1024);
  /* This only works if the title and its tags are on one line */
  if (preg_match ("@\<title\>(.*)\</title\>@i", $line, $out)) {
  $title = $out[1];
   break;
 }
}
fclose($file);

where $url is the url of the website
