 * I don’t know anything about php so I need help from you guys. I need to do something
   like this in the loop:
 * if (comment_number!=0) {
    // do something here }
 * The question is, how do code the test condition?
    Thanks in advance!

 * I tried that actually, but it displays the number, instead of returning it as
   a value.

 * Hm, even if you set it as `<p>This post currently has <?php comments_number('
   no responses','one response','% responses'); ?>.</p>` ?

 * You can look at `$comment_count_cache[$post->ID]` for that. It should be populated
   for you.

 * Thanks guys. I’ll try that later to see if it works. I might be back with more
   questions though. =)

 * markjaquith: It worked like a charm. But I’m just wondering, how would I find
   such tags? I mean how am I supposed to knwo it if it’s not in the Codex?
    Thanks
   again!

 * You have to open the related file and peruse the source code yourself, and examine
   what does what and how.
