Reply to Re: [PHP] Virtual includes of PHP into SSI pages. — PHP

For this to work you must set html and shml as a php file extension in
apache.

This is because shml includes are made before it reaches apache output, so
if you have file "a" including file "b" it the same as having only one file
"a" with copy and paste of file "b" with shml file extension and thus this
is never parsed to php.

Hope i´m making any sense here, bad english
