Best PHP version for vB 4.2.2

[TheAdminMarket]

Hello,

I want to upgrade my PHP (5.3.3) and I'm wondering which is the best PHP version which works fine with vB 4.2.2. I mean without that warning messages during installation/use, even if I know how to hide them.

Thank you

PHP 5.4 is the best for vB4.2.2pl1 (which I'm running)
You can run PHP 5.5 with vB4.2.3beta2 (we will upgrade to this in the next few weeks)
