Parsing .shtml files for SSI + PHP code?

[DoST]

How can I make my server parse .shtml for both Server Side Includes and PHP code? I'm using Apache. Any help will be greatly appreciated.

Thanks

check out the virtual call in PHP.

Unfortunately you cannot have php output a <!--#include virtual="blah.html"--> type string and expect that to be parsed as a SSI.
