A good and very effective tutorials for PHP. Specially for the beginners.
Practical PHP Programming – now updated for PHP 5.2. This is the definitive
source for the book from now on, and you’ll be pleased to know the entire
book is hosted on a super-fast server so you should never have access troubles again.
Once you are up and running with your own PHP programming, you'll find that the majority of your scripts are variables, operators, and under ten functions that you use commonly.
In this chapter we will be looking at the different types of variables used in PHP, which to use and when, and also how to convert between the different types. We'll also be looking at operators - these are things that have any effect on variables, such as adding, subtracting, and multiplying.
This chapter is designed to give you complete information on how PHP's variables work - you needn't understand some of the more complicated parts, such as references or variable variables, unless you really want full comprehension of the language.
