OK I've got here a problem which really made me scream for the last 6 months! I can't go home without solving it since my wife really is fed up with all my yelling...
I've got 2 files called frame.php and content.php
In content.php, I defined a variable with the help of the "<<< >>>" signs. In this variable I put some php code.
Then I include the frame.php file.
This file contains my standard head and bottom sections.
Between these sections, I want to display my variable with an "echo" function.
It works great, except for one tiny, tiny detail :
the php code inside my variable is not parsed ... Aaaarrrgghhh !
