PHP is a server scripting language, widely-used free and a powerful tool for making dynamic and interactive Web pages. PHP is a efficient alternative to competitors such as Microsoft's ASP. PHP files can contain text, HTML, CSS, JavaScript, and PHP code
<?php
//PHP code goes here
?>
A PHP file normally contains HTML tags, and some PHP scripting code. Below, a example of simple PHP file, with a PHP script that uses a built-in PHP function "echo" to output the text "Hello World!" on a web page: <!DOCTYPE html>
<html>
<body>
<h1>My first PHP page</h1>
<?php
echo "Hello World!";
?>
</body>
</html>
