php 5.2 requirements for 3.0 and 3.1B

[saksu]

I searched filter_var in cms files, it appers to be a proble on admin panel. That is acceptable for me.

Code:

/var/www/wcrl3# find . -exec grep -q "filter_var" '{}' \; -print
./admin/template/error_checking.php
./admin/inc/basic.php
./admin/inc/template_functions.php
