How can I get at the node object from a PHP page? I've tried using node_load and arg(1) but that only works if I'm actually viewing the page, not when listed as a teaser.

The node object ($node) is only defined in page.tpl.php and the trick of looking at arg(0) == 'node' and using arg(1) as the nid only works when viewing a single node on the page. So it would probably help if you explained what you are trying to do and people would be better able to help you.

I need to be able to get the current node id and pull some related data from a table and display this in the body. Looks like I can't do it as there is no way to get the real current node.

You can write a module that implement the nodeapi hook which for your purposes would be called when a node is viewed ($op == 'view') at which point you could add to the body of the node.

Second approach is to handle it in node.tpl.php and add the information when the node is displayed.

So a possible solution would be to use a regular expression to replace some marker text in the body with the content I want? For example:

function mymodule_nodeapi(&$node, $op, $teaser = NULL, $page = NULL) {
  switch ($op) {
    case 'view':
      $node->body = preg_replace('\MARKER\', 'replacement content', $node->body);
      $node->teaser = preg_replace('\MARKER\', 'replacement content', $node->teaser);
      break;
  }
}

In this case because you want to replace a marker you could also use the filter hook. The filter hook would be useful if you wanted to be able to specify options/parameters for what should be included.

And the filter hook has access to the node object? If it does that would be perfect.

Actually the body/teaser (depending on context), it does not have access to the complete node (or even "know" it is being used to filter a nodes content.
