Some code review tips (apply when writing software as well)

  • implement the design completely and correctly
  • handle reasonable error conditions
  • follow PSR coding standard (naming, indentation, white spaces usage etc...)
  • regularly commit (sizeable but working changes) so the code reviews are not complex and long
  • write unit tests
  • do peer code reviews
  • remove any code duplicities (extract repeated code blocks to a method or procedure)
  • less code is better (try to use functions instead of loops)
  • beware of deep nesting (conditions, loops), preferably nest only 1-2 levels
  • create well-structured code, consistent in style and formatting
  • get rid of all leftover stubs, test routines and any unnecessary code (dead code) or testing code
  • get rid of all redudant / unused variables
  • name the variables, constants, procedures, classes and methods in a descriptive way (meaningful, consistent and clear names)
  • do not use (hardcoded) magic numbers or strings, instead use variables, config options or constants
  • use OOP principles when applicable (interface, trait, abstractions, static)
  • keep functions outside of loops
  • do not copy extra variables
  • follow DRY principle
  • use array literals "[" .. "]", instead of array(..)
  • use proper directory structure and separate the code into files

We'll add some other points later related to data sanitization, design patterns etc.
