Jani Hartikainen's Blog:
Three PHP mistakes that will cause you debugging nightmares

Jani Hartikainen has posted about three simple, but hard to find, mistakes that can cause you endless frustration if you're not looking in the right places.

Here's his list:

  • Semicolon after a while - a small problem with big (infinitely looping) consequences)
  • empty() and magic __get method - __get will hit first, then empty
  • Missing semicolon after break or continue - a classic that can make switches and evaluations difficult to debug

Comments on the post include a few others: working with variables by reference, comparisons with == versus === and strpos finding the first character in a string.
