I've found free editor in Puppylinux (Geany0.12), which able to save as PHP so that fun for me.
So today is the first day I try. I've edit code in edit as below
and I save in new directory name suntphp as screen below.
after run with SeaMonkey by calling address file:////usr/suntphp/testphp.php
, which able to show only HTML line so sure that we need install php in to puppy linux.
