As highly recommended as the above resource is, could make a suggestion, try to think of your own exercise to do as you are learning. Think of a project that you would like to complete yourself that differs from the the exercises listed in the books.
I found that by creating my own project as I was learning, I had utilised the references within the books, but I felt I became more involved in learning as I was building something I wanted. And when I had completed a task contained within the book, it felt very rewarding as I knew I built the project myself. You can easily copy the exercises in the book and KNOW that they are going to work because it works in the book, but when you are developing your own project, you learn from the tutorial, but if you project doesn't work, you will learn more when you try to fix the error that has occurred. It gives you a greater UNDERSTANDING of PHP not just KNOWING
You can refer to www.w3schools.com and www.php.net .
For manual you can download php manual, mysql manual.
Read those. Do code as much as you can, face more problems.
Try to solve those. One day you will be familier with all the problems
and it is what you really learned than just reading books.
