I am learning PHP/MySQL and I hope that I will complete my all tutorials within 2 or 3 month or maximum 6 month.
When first time you started coding, Do you use books while making your software?
I mean we can learn full course but can't remember every function and we will need a reference book or tutorial to remember it again and again so you use book or online site while making php software?
I've used books in the past for other languages, and still keep a few handy for things I don't use that often. The problem with some is that they become outdated very quickly, so you don't know if you're following best practices and such anymore. These days I mostly use the internet to search around. Depending on the language will sometimes determine the site, but for general troubleshooting Stack Overflow is great.
Years ago I had and used a book called "the Unix bible", it was a good reference.
That was back in the early 90's ,... oh and then "Dos for Dummies", as well, when it was
first published
I'm a self taught developer and I found the best way to learn is to take a Content Management Framework or Content Management System and backwards engineer it. I think it takes many years to learn and remember many php functions, as long as you get the basic ones and then just use the PHP reference website. This website is good to ask for help and find answers to issues you might be having that people have had many times before you. It's saved my life many, many times!
