The class PhpManager has 32 non-getter- and setter-methods. Consider refactoring PhpManager to keep number of methods under 25.
Open

class PhpManager extends BaseManager
{
    /**
     * @var string the path of the PHP script that contains the authorization items.
     * This can be either a file path or a [path alias](guide:concept-aliases) to the file.
Severity: Minor

Since: PHPMD 0.1

A class with too many methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects. By default it ignores methods starting with 'get' or 'set'. The default was changed from 10 to 25 in PHPMD 2.3.

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) {

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 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.

          }

    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.

    // Cyclomatic Complexity = 11
      class Foo {
