Standard template for output

hi all, is there a way to use a standard template for all my web pages, such that _any_ php script just have to include the file and output whatever is processed at a specific location in the template? i'm trying to design my app such that any design changes can be done in one file. Current Method (every php script must have a require at the top and bottom) : <? require("header.inc") ?> <? ... code ... ?> <? require("footer.inc") ?> Ideal method : <? ... code ... ?> <? Output to template ?> Here is a sample template : <HTML> <BODY> <B>Standard Header</B> <!-- All output must be here --> <B>Standard Footer</B> </BODY> </HTML> -ken
