I want to learn PHP and MySQL. What books should I read? I like programming and have just started learning C language, but I also want to learn PHP and MySQL. Should I learn HTML and CSS first? Then start learning PHP and MySQL? Also, what textbooks do you recommend? ——Solution——————–HTML and CSS are relatively simple and can be learned together. You don’t have to learn it yet, but you will definitely understand it in the future. It’s not difficult. As for books, here are my recommendationshttp://blog.csdn.net/phpnewnew/article/details/6896582 ——Solution——————–Complete sure. The w3c website is good.
