PHP

What PHP version can I expect?

5.3.10

In the near future we hope to make to give you the option to select newer versions.

How much memory do I have per page request?

This depends on your plan. The lowest plan gives you 64MB. Beyond that you can get up to 128MB upon request. Note that this is memory per page request, the memory available to PHP, not the total amount of memory on our servers, or the total amount of memory you have across all page requests.

128MB appears to be plenty even for views heavy sites. If you really need more than 128MB per page request, you will need your own servers.
