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
}

A class with too many dependencies has negative impacts on several quality aspects of a class. This includes quality criteria like stability, maintainability and understandability

Example:

class Foo {
/**
* @var \foo\bar\X
*/
private $x = null; /** * @var \foo\bar\Y */ private$y = null;

/**
* @var \foo\bar\Z
*/
private $z = null; public function setFoo(\Foo$foo) {}
public function setBar(\Bar $bar) {} public function setBaz(\Baz$baz) {}

/**
* @return \SplObjectStorage
* @throws \OutOfRangeException
* @throws \InvalidArgumentException
* @throws \ErrorException
*/
public function process(\Iterator $it) {} // ... } #### The method setDownloadHeaders has a boolean flag argument$inline, which is a certain sign of a Single Responsibility Principle violation. Open

Since: PHPMD 1.4.0

A boolean flag argument is a reliable indicator for a violation of the Single Responsibility Principle (SRP). You can fix this problem by extracting the logic in the boolean flag into its own class or method.

Example:

class Foo {
public function bar($flag = true) { } } #### The method redirect has a boolean flag argument$checkAjax, which is a certain sign of a Single Responsibility Principle violation. Open
