So I have been using an ORM for the past 3-4 months and have developed a website using it in par with a framework.
My curiosity is grown larger and what ORM really are, so i decided to start building one from scratch but did some research yesterday and today and im still very confused on where to start from and I don't seem to be able to find a good guide to start from.
Lately my love for MongoDB has been growing so it would be even more fun and interesting if I can have php + MongoDB ORM.
Do you guys have any starting points? Like books, slides or articles where I can have a look at and start.
If you guys want to add anything please tell me! I really want to learn the deep end of a infrastructure of a website!
