Code

function intlinks_is_node_path($path) {
  if (strpos($path, 'node/') === FALSE) {
    return FALSE;
  }

  // Trim any leading slash from original link.
  $path = ltrim($path, '/');

  // This function should also deal with the possibility that it was passed a
  // path that still has a "anchor" text appended to it. The part
  // after the slash should all be numeric for the next test.
  $path_parts = explode('#', $path);
  $path = $path_parts[0];

  // Now the path is trimmed of anything extraneous.
  $path_parts = explode('/', $path);
  if (count($path_parts) == 2 && ctype_digit($path_parts[1])) {

    // $path_parts[1] is the node id.
    return $path_parts[1];

  else {
    return FALSE;
