PhPBB TPL vs PHP

[basslion]

What exactly is a TPL file and why does the basic setup of PHPBB not have these files in any directories, but it seems all the cool templates use them?

TPL file is a TemPLate file.

By default phpBB does have a set of TPL files in templates/subSilver/ directory.

With relation to php, i dont really know why standard template engine does not support PHP.
