Phpinclude questions (filburt?)

[Dean C]

1/ If i'm calling templates in phpinclude, i don't want it adding a query to every page so should i use the $templatesused variable in the phpinclude too?

2/ How do i limit the code to running only when on a certain file:

e.g.

PHP Code:

$lala = echo("blah"); 


If i wanted that only to apply to showthread.php what would i do ?

Thanx
