PHP
php(1) (PHP: Hypertext Preprocessor) is a scripting language designed for dynamic web pages.
The current version is 8, but older (unsupported) versions see continued use. The language has evolved rapidly and porting between versions can be a difficult task.
Example
<?php echo 'Hello, World!';
Embedded Example
php(1) can be embedded into web pages, if the web server supports it.
<!DOCTYPE html>
<html>
<head>
<title>PHP "Hello, World!" program</title>
</head>
<body>
<?php
echo '<p>Hello, World!</p>';
?>
</body>
</html>
Installation
Most Linux and BSD distributions will offer a php package, as well as versioned packages (like php7).
