PHP Dos and Don’ts aka Programmers I Don’t Like

I will find you meme - Taken (2008)I am sure every PHP developer has a colleague they hate because he/she coded the application they started maintaining. This is mostly because the code is old. New standards become common, they learn what they used to do was inefficient, unreadable, or complicated. As PHP is a language that changed significantly over the years, code written a few years ago will certainly look outdated.

That being said, this post is not about the old PHP code. This post shows how to be a bad programmer even when following standards. Please don’t be this person.

  1. Too many nested if statements
  2. Extra brackets and braces
  3. Unnecessary casting

  8. Long lines
  9. Long if-else blocks
  10. Wrong function / class name casing
  11. Lack of coding standards
