mysql, just read "High performance mysql".

Design patterns can be found in "going deep into PHP: object-oriented, patterns and practices"

at the bottom, you can take a look at C, the recommended book for learning: "C language programming: modern methods"

High concurrency, there is a book called "Seven weeks and Seven concurrency Model"

you can learn about it and read which one you like.
