Answered EVO - PHP version upgrade to 5.6 for snippets etc.?

Hi,

I developed some PHP code (snippets) and I have a problem with that arrays can not be defined in class constants (prior to PHP 5.6 atleast). There is a workaround though, but I prefer to code with PHP 5.6 or above inside EVO for my snippets, etc.. Is that possible? If so how, an upgrade? Any concerns I have to keep in mind when doing that? Thanks.
