not that we would change anything - I am just personally curious: which PHP version do you have installed on the web server you use for your productive OXID eShop installation?
I personally run 5.3.10 on Ubuntu on localhost…
To find this out, please go to Admin -> Service -> System info and search for “PHP Version” with CTRL-F
We are using 5.3.x for all new customer projects. We prefer 5.3.x because our non-ecommerce work uses frameworks that require 5.3.x. Also, we use Debian as our hosting platform & the support for Debian 5 (with php 5.2) has ended, so we will be migrating existing customers to Debian 6 (with 5.3.x) during 2013. We leave the choice of the precise version of php up to Debian, which we update monthly.
On my Systems i compiled PHP 5.2, 5.3 and 5.4, for my own Applications im using only PHP 5.4, for oxid 5.2, but this depends on some Modules we use. I think until Q1/13 i can upgrade all Modules.
I had to downgrade from 5.4 to 5.3 at my development system to be able to use OXID PE. I’d really like it if you would provide an ionCube version, since ionCube supports PHP 5.4 and Zend could not even tell me a date when 5.4 will be supported.
