PHP: Hypertext Preprocessor
PHP: Hypertext Preprocessor (or simply PHP) is a server-side scripting language and for the most part it is designed for Web development, and also used as a general-purpose programming language.
PHP first code - how to create - example
Used initially to produce dynamic web pages, it is widely used in the development of web pages and web applications. It is mainly embedded in HTML, but starting with version 4.3.0, it can also be used in the "command line" (CLI) mode, allowing for the creation of independent applications.
It is currently among the most popular open source projects (thanks in part to the similarity of its syntax to the C language).
The code is interpreted by a web server with a PHP processor module that generates the resulting web page.
Example 1: First PHP code
<!DOCTYPE html>
<html>
<title> First PHP code</title>
</head>
<body>
<?php
echo "Hello people! <br /> This is a simple PHP code";
?>
</body>
</html>
<html>
<title>
</head>
<body>
</html>
PHP language - Example - How to create
If you ever accessed a website that gave you the option to log in, you would probably run a server-side script language; surely PHP would be running, due to its great impact on the market. This language was originally created by Rasmus Lerdorf in 1995 and is currently still being developed with new functions by the PHP group.

Basically, PHP allows static pages to become dynamic (although it is much more than that). The name "PHP" is an acronym that means "PHP: Hypertext Preprocessor", in Spanish "PHP: Hypertext Preprocessor".
The word "hypertext" means that PHP makes changes before the content (such as the HTML page) is created. This allows developers to create powerful applications that publish blogs, control hardware remotely or run powerful websites like Wikipedia or Wikibooks.
Of course, these sites use other technologies in conjunction with PHP, for example a database server such as MySQL.

Another PHP code example
<?php
$a = 0 ;
$b = 0 ;
for ( $i = 0 ; $i< 5 ; $i++ )
{
$a += 10 ;
$b += 5 ;
}
echo ( "At the end of the loop a = $a and b = $b" ) ;
?>
$a +=
