The Weighted Method Count (WMC) of a class is a good indicator of how much time and effort is required to modify and maintain this class. The WMC metric is defined as the sum of complexities of all methods declared in a class. A large number of methods also means that this class has a greater potential impact on derived classes.

Example:

class Foo {
public function bar() {
if ($a ==$b)  {
if ($a1 ==$b1) {
fiddle();
} elseif ($a2 ==$b2) {
fiddle();
} else {
}
}
}
public function baz() {
if ($a ==$b) {
if ($a1 ==$b1) {
fiddle();
} elseif ($a2 ==$b2) {
fiddle();
} else {
}
}
}
// Several other complex methods
}

# 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"

#### The class User has 16 fields. Consider redesigning User to keep the number of fields under 15. Open

class User extends Component
{
const EVENT_BEFORE_LOGOUT = 'beforeLogout';
Found in framework/web/User.php by phpmd

Since: PHPMD 0.1

Classes that have too many fields could be redesigned to have fewer fields, possibly through some nested object grouping of some of the information. For example, a class with city/state/zip fields could instead have one Address field.

class Person {
protected $one; private$two;

#### The method renewAuthStatus() has an NPath complexity of 432. The configured NPath complexity threshold is 200. Open

$id =$session->getHasSessionId() || $session->getIsActive() ?$session->get($this->idParam) : null;  Found in framework/web/User.php by phpmd Since: PHPMD 0.1 The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity. Example: class Foo { function bar() { // lots of complicated code } } #### The method switchIdentity() has an NPath complexity of 208. The configured NPath complexity threshold is 200.

The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity.

Example:

class Foo {
function bar() {
// lots of complicated code
}
