[Typo3] PHP version to use with Tzpo3

[Tomaz Bartol]

Hi guys,

just joined, a wanna-be-typo3 user :-)

On the Typo3 site I've seen that PHP 4  is always mentioned to be the
requiret middleware. Is that PHP 4 exactly or PHP 4 and higher?
Anyone has any experience in running Typor with PHP 5 (that is my server's
default)?

Thanks a lot,
tomba
