Lecture 2: What is PHP?

PHP is one of the most (if not the most popular) server-side programming language on the web today, with more than 240 million websites using it (as of January 2013 — according to Wikipedia).

Websites like Google, Apple, Facebook and YouTube utilize PHP. Popular Content Management Systems (CMS) like WordPress, Drupal, Joomla and Expression Engine all rely on PHP.

PHP stands for “Hypertext Preprocessor” — I know, right? I don’t get it either…

PHP can be used as a stand-alone programming language to create robust applications, or it can be used within HTML code to create dynamic websites (which is the goal of this course).

PHP runs on a “server”, and in order to use PHP on your own computer when developing a website, you’ll need to have a server installed on your machine — don’t worry about this part, it’s quick & painless to get set up, and it doesn’t cost you a penny.

I’ll be covering the tools you’ll need in an upcoming lecture.

Also, I will be frequently referencing PHP.net throughout the duration of this course, and I recommend you bookmark it for easy access.

Stay tuned, because in the next lecture I’ll give you a quick rundown of some of the cool things PHP can do!

See you there!

  1. …you use language but no examples. like what is a dynamic website? what is a CMS,,? what is a 'robust' application? ,

  2. I want to build one of the biggest companies using php…you would be in my ife documentary on learning php

  3. I believe when PHP was first developed it was named PHP meaning, Personal Home Page, now it stands for Hypertext Preprocessor.

  4. Hello Brad.
    PHP was an acronym for "Personal Home Page" which is the PHP's name prior to version 3.x. Around version 3.x the meaning of the acronym changed to (a recursive acronym): "PHP: Hypertext Preprocessor", but even then people used the first meaning for a few more years (up to version 4.x if I remember correctly… it was a while ago). 🙂
    Regards. 🙂
