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"

Reduce the number of returns of this function 4, down to the maximum allowed 3. Open

- Read upRead up
- Exclude checks
Having too many return statements in a function increases the function's essential complexity because the flow of execution is broken each time a return statement is encountered. This makes it harder to read and understand the logic of the function.
Noncompliant Code Example
With the default threshold of 3:
function myFunction(){ // Noncompliant as there are 4 return statements if (condition1) { return true; } else { if (condition2) { return false; } else { return true; } } return false; }

Remove the unused function parameter "$array2". Open

Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.
Noncompliant Code Example
function doSomething($a, $b) { // "$a" is unused return compute($b); }
Compliant Solution
function doSomething($b) { return compute($b); }
Exceptions
Functions in classes that override a class or implement interfaces are ignored.
class C extends B { function doSomething($a, $b) { // no issue reported on $b compute($a); } }

Define a constant instead of duplicating this literal "array" 3 times. Open
self::assertContainsOnly($arrays, 'array', __FUNCTION__);
- Read upRead up
- Exclude checks
Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
Noncompliant Code Example
With the default threshold of 3:
function run() { prepare('action1'); // Non-Compliant - 'action1' is duplicated 3 times execute('action1'); release('action1'); }
Compliant Solution
ACTION_1 = 'action1'; function run() { prepare(ACTION_1); execute(ACTION_1); release(ACTION_1); }
Exceptions
To prevent generating some false-positives, literals having less than 5 characters are excluded.
