Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

    CyclomaticComplexity

    Since: 0.1

    Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.

    Example

    // Cyclomatic Complexity = 11
    class Foo {
    1   public function example() {
    2       if ($a == $b) {
    3           if ($a1 == $b1) {
                    fiddle();
    4           } elseif ($a2 == $b2) {
                    fiddle();
                } else {
                    fiddle();
                }
    5       } elseif ($c == $d) {

                    fiddle();

                }
            } else {
                switch ($z) {
    9               case 1:
                        fiddle();

    IfStatementAssignment

    Since: 2.7.0

    Assignments in if clauses and the like are considered a code smell. Assignments in PHP return the right operand as their result. In many cases, this is an expected behavior, but can lead to many difficult to spot bugs, especially when the right operand could result in zero, null or an empty string and the like.

    Example

    class Foo
    {
        public function bar($flag)
        {
            if ($foo = 'bar') { // possible typo
                // ...
            }
            if ($baz = 0) { // always false
                // ...
            }
        }
