        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"

        If you throw a general exception type, such as ErrorException, RuntimeException, or Exception in a library or framework, it forces consumers to catch all exceptions, including unknown exceptions that they do not know how to handle.

        Instead, either throw a subtype that already exists in the Standard PHP Library, or create your own type that derives from Exception.

        Noncompliant Code Example

        throw new Exception();  // Noncompliant

        Compliant Solution

        Define a constant instead of duplicating this literal "references/" 3 times.

        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.

        Rename "$osTag" which has the same name as the field declared at line 19.

        Shadowing fields with a local variable is a bad practice that reduces code readability: it makes it confusing to know whether the field or the variable is being used.

        Noncompliant Code Example

        class Foo {
  public $myField;

  public function doSomething() {
    $myField = 0;
    ...
  }
}
