NPathComplexity
Since: 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.

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

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() {

Cognitive Complexity is a measure of how hard the control flow of a function is to understand. Functions with high Cognitive Complexity will be difficult to maintain.
See
Reduce the number of returns of this function 4, down to the maximum allowed 3. Open
private function _detectJsonRequest()- 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;

Define a constant instead of duplicating this literal "deletetoken" 3 times. Open

- 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.
