The class BaseYii has 12 public methods. Consider refactoring BaseYii to keep number of public methods under 10. Open
class BaseYii
{
/**
* @var array class map used by the Yii autoloading mechanism.
* The array keys are the class names (without leading backslashes), and the array values

TooManyPublicMethods
Since: 0.1
A class with too many public 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'.
Example

The class BaseYii has an overall complexity of 64 which is very high. The configured complexity threshold is 50. Open

Function setAlias
has a Cognitive Complexity of 18 (exceeds 5 allowed). Consider refactoring. Open

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"

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() {
2 if ($a == $b) {
3 if ($a1 == $b1) {
fiddle();
4 } elseif ($a2 == $b2) {
fiddle();
} else {
fiddle();
}
5 } elseif ($c == $d) {
6 while ($c == $d) {
fiddle();
}
7 } elseif ($e == $f) {
8 for ($n = 0; $n < $h; $n++) {
fiddle();
}
} else {
switch ($z) {

fiddle();
break;
10 case 2:

The method getAlias has a boolean flag argument $throwException, which is a certain sign of a Single Responsibility Principle violation. Open
public static function getAlias($alias, $throwException = true)
- Read upRead up

BooleanArgumentFlag
Since: 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) {
}
}

Avoid unused local variables such as '$path'. Open
foreach (static::$aliases[$root] as $name => $path) {

UnusedLocalVariable
Since: 0.2
Detects when a local variable is declared and/or assigned, but not used.

}
}

ShortMethodName

public function a( $index ) { // Violation
}
