PHPMaster.com has a new article about a practice that's becoming more popular in recent years to help increase the quality of code that comes out of development - code reviews.

Every developer knows the pain of banal mistakes. A wrong attribute here, a misspelled property there, an accidentally duplicated line of code which you missed because of the coffee-fueled 16 hour hackathon you've been on. [...] Code review is simply the act of having someone else look at your code to find the mistakes you missed.

The tutorial talks about the types of code reviews (three of them with varying levels of involvement) as well as some best practices to follow in your reviews like:

  • Know your common mistakes and actively fight them.
  • Peer code review means being reviewed by someone of equal or greater skill.
  • Collect metrics.
  • Be mindful of the social aspect - finding bugs is good, not bad!
