Comments are only intended for the programmer. They will not be displayed or executed. They identify as part of the program without interfering in the program. Comments are among the trivial elements in the success of a program; and this is why it is important to use them with intelligence.

This chapter presents two important principles to assimilate: the condititions and loops. This first concept is especially important since it allows to perform a series of actions depending on the conditions being tested. As for the second, it allows to repeat N times a series of actions, and in very short time (at human scale). The advantage of the arrival of the computer is to make life easier for users performing tasks that they can not fulfill. If you ask a person to count from 0 up to 1000, it will take several minutes while a computer will process this transaction in milliseconds (or even a few nanoseconds as its computing power). Then immediately understand the benefits of computing.

The conditional structure "foreach" when you allowed to browse the contents of a table. With version 5 of PHP, you can now browse an entire object to retrieve its properties.

Among the most important concepts of the programming is the concept of variable. Like any language, PHP handles data. For a dynamic site, these data are variables. In addition, they may be of different types, such as text string, as you have used the echo statement in the form of whole or decimal numbers or as true or false boolean values (TRUE or FALSE). These basic types are the most used, but there are others who may be compounds types, such as arrays and objects, or specific types, as resource or NULL. . We will see that the variable part of the mechanisms which make a dynamic application. Let's get into the thick of it.

As in most programming languages, it is possible to create your own PHP functions that complement the native functions. This allows performing particular operations that are redundant in the application, and solve a problem by breaking it into several small problems and solutions.

In programming, PHP allows you to define constants, it is often necessary to define data structures whose value must not change during program execution. These data structures are typically what is known constants. The most famous mathematical constants is for instance the PI number whose value is approximately 3.1415926535898. Note that PHP natively integrates the M_PI constant. This can then be used for any calculation of circumference.
