Dear Lady/Sir, I need of free informations on Your software, because I am absolutely non expert (and not very rich actually) and I did free download (GNU) of this program only for Study better php language, as indicated on a e-book (2015) with exercises. I resume what I would like to know from You : 1. I accepted the licence on line but I read only the first part.Can I have a licence in pdf format? 2. I’m very honest, but I don’t know, actually, international laws on php and similar. Can I use, after training, Your program for commercial use? 3. Can You give me a little general explanation on the system? 4. (Last, but not least) How can insert my first php script in a page; how can I create the first page? The following issues : I will study more only if I will know that it is all legal from my position. Thank’s for attention and sorry for my temporarely ignorance (also in writing You). All this system, like “open source”, is a very important action of Your Society (if I understood well). I’ll wait an answer. Best regards Luca
