PHP

PHP is cross-platform, HTML embedded, server-side web scripting language.

• Cross-platform - You can run most PHP code without alteration, on computers running many different operating systems. A PHP script that runs on Linux will generally run on Windows as well.
  
• HTML embedded - PHP code written in file containing mixture of PHP instructions and HTML code.
  
• Server-side - The PHP program we write are run on a server - specifically, a web server.
• A web scripting languagge - We run programs via web browser. We access the web server on which they reside, and this runs the program, sending any resulting output back to the browser.
