PHP Course Introduction Notes

Overview of the Course

• New version of the PHP course.
• Course aims to be better structured than previous iterations.
• Focus on beginners with no prior programming experience.
• Emphasis on making the course easy to digest and not overwhelming.

What is PHP?

• PHP stands for Hypertext Preprocessor.
  • It's a recursive acronym.
• Mainly used for web development but can also create desktop applications.
• Can be easily embedded within HTML.
• Considered a server-side language:
  • Runs on the server, not in the browser (unlike HTML, CSS, JavaScript).
  • PHP code is not visible in the browser.

Is PHP Dead?

• Contrary to some beliefs, PHP is not dead:
  • As of 2023, over 78% of websites use PHP as their backend language.
• Criticism stems from PHP being primarily web-focused, while languages like Python have broader applications.
• For web development specifically, PHP is highly recommended.

Popular Websites Using PHP

• Facebook
• Wikipedia
• Canvas
• WordPress (most popular content management system)
