Alex Netkachov's Blog:
PHP micro-optimization tips
March 10, 2009 @ 08:47:38

For those trying to squeeze the absolute most out of their applications, check out these suggestions from Alex Netkachov on a few "micro" kinds of things that could help speed things up in the long run.

Why "micro-"? Because changing logic of your application may give you much better performance boost then applying all these tips. But they still can make your code better. You always need to output something, why do not use "echo" instead of "print"?

He has a list of about thirty things you can do including:

  • calling a function is faster then calling a static method
  • accessing an initialized variable is faster then accessing an uninitialized variable
  • avoid @ (error control operator)
  • adding method parameter type hint increases calling time
  • cache page output or result of resource-consuming functions
  • pre-increment (++$i) is faster then post-increment ($i++)
  • an array is a faster alternative to a class with several fields

These hints aren't going to make amazing differences in your code, but they could help get you out of a sticky place where your code just doesn't want to behave.
