From 4.1.0 (or 4.2.0)

Default register_globals in php.ini is off
This disables automatic forms input name to PHP vars function
(Eg.<input name=simpletext > => in php the input value is available as $simpletext with register_globals on )
Therefore, you need to access below Globals to access them

Also, short_open_tags is off
This disables <? ?> php tag. so you need to use <?php ?>.
