PHP Intro

What is PHP?

PHP is an acronym for "PHP: Hypertext Preprocessor". It is a widely-used, open source scripting language that is especially suited for web development and can be embedded into HTML.

What can PHP do?

  • Generate dynamic page content
  • Create, open, read, write, and close files on the server
  • Collect form data
  • Send and receive cookies
  • Add, delete, modify data in your database
  • Control user-access
  • Encrypt data

Note: PHP runs on the server, and the plain HTML result is sent back to the browser.
