#Hello World in PHP

<div class="text-success lead">
PHP is a widely used, general-purpose scripting language that was originally designed for web development 
to produce dynamic web pages. For this purpose PHP code is embedded into the HTML source document and 
interpreted by a web server with a PHP processor module, which generates the web page document.
