I'm looking for some up to date tutorials for using bitcoin for a payment system. I have only used electrum and dont have the space for a full node on my system for the full blockchain required to use bitcoind. I want to build a system that doesnt rely on blockchain.info and gives me complete over private keys. I'm trying to make something where each customer get their own address generated for each payment then my server can verify the transactions after so many confirmations. The bitcoin wiki is seriously out of date and isnt straight forward on how to use it without needing a full node. My final site will be on a Linux VPS and test server is on Linux laptop without enough memory for full blockchain. I've found the easybitcoin.php library and tried using it but of course doesnt work right because bitcoind cant download full blockchain and I'm not understanding how to use bitcoin.conf

I'd really love to find a tutorial that will teach me how to make this system without needing a full node starting all the way from how to set up bitcoin in PHP.
