thanks for this idea!

I used it to create a simple post counter for commentboxstyled.php.
I added to the script the following:

# add page variable {$PostCount},
# counts message items per page
$FmtPV['$PostCount'] = 'StringCount($pagename,">>messagehead<<")';
function StringCount($pagename,$find) {
   $p = ReadPage($pagename, READPAGE_CURRENT);
   return substr_count($p['text'], $find);
}

Then one can use the new page variable {$PostCount} on any comment
page or in a pagelist format template (I've done it for the simple
forum), which shows the number of posts on the page.

A forum pagelist format template with an extra column for posts
counted can look like this:

!!!fmt=#forum
forum topics in table format 
[@
[[#forum]]
(:if equal {<$Group}:)
(:table class=forum width=100% :)
(:cell style="background:#e5e5ff;padding-left:5px" :)'''Topic'''
(:cell style="background:#e5e5ff;padding-left:5px" :)%thd%'''Posts'''  
(:cell style="background:#e5e5ff;padding-left:5px" :)%thd%'''Last Posted''' 
(:cell style="background:#e5e5ff;padding-left:5px" :)%thd%'''By''' (:if:)
(:cellnr style="background:#eeeeff;padding-left:5px" :)[[{=$FullName}|+]] 
(:cell style="background:#eeeeff;padding-left:5px" :){=$PostCount}
(:cell style="background:#eeeeff;padding-left:5px" :){=$LastModified}
(:cell style="background:#eeeeff;padding-left:5px" :){=$LastModifiedBy} 
(:if equal {>$Group}:)
(:tableend:)(:if:)
