Where do I put PHP to get a term ID? I've been trying to figure our how to get a term ID of a taxonomy term I created, and I found a little bit of php that looks like it should work. However I have no idea where to put it to get a response. 

I'm working on a D6 site that needed updating and already found this script

$term = taxonomy_get_term($tid);
$name = $term-&gt;name;


Any pointers?
That code won't work.  The first line is using the $tid to load the term, obviously that won't work if you don't know the Term ID in the first place.

You don't need to use any PHP to get a taxonomy terms ID. Just goto the edit page of that term and look at the url. It will be /taxonomy/term/TID/edit
