The vast majority of dynamic websites or applications need to reuse parts of identical code in several places of the same page, or in several different pages. This is the case for example libraries of user functions or configuration files. Rather than rewrite each time the code, there are functions (actually language constructs) that can import and execute the code reuse in the page. These are the include () and require ().

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.

PHP was invented by Rasmus Lerdorf in 1994 for his own use (posting his resume in this case). Formerly abbreviation for Personal Home Page now become Hypertext Preprocessor, PHP is becoming a standard in the world of web programming with its performance, reliability, flexibility and speed.

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.

As you all know, any PHP script must be surrounded by specific tags. They allow the interpreter to know where in the file is PHP code to execute. On ecomputernotes.com, all presented scripts use the <? Php and ?>; and it is not by chance ...

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.
