Whenever I view a node page, I want to call a function but I'm not sure how to do that.

I was thinking I should use hook_menu() and declare the path as node/%, and attach a callback function to that path. Is that the right way, or is there a correct/better way?

    Yes the answer's very simple, but I'm not sure why that makes this a bad question. The downvote seems unnecessary IMO. I edited to clarify and make it obvious that you've though about this yourself, hopefully that'll be enough to appease the nay-sayers :) – Clive♦ Aug 23 '13 at 10:18
  • I must admit Clive's edit significantly improved readability of this question :) +1 from me. Questions simple to answer when you know the answer are not always bad, it's sometimes hard to search them on the net or drupal.og docs. – Mołot Aug 23 '13 at 11:06

You can implement hook_node_view()

Act on a node that is being assembled before rendering.

e.g.

function MYMODULE_node_view($node, $view_mode, $langcode) {
  if ($node->type == 'the_type' && $view_mode == 'full') {
    // Call your function here.
    my_function($node);
  }
}

Rules module can also react to URL access. You can specify an action supposed to happen on event if condition is true.
