Define a constant instead of duplicating this literal "logSummary" 13 times.

Severity: Critical
Found in src/Debug/Data.php by sonar-php

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.

Severity: Major
Found in src/Debug/Framework/Yii2/LogTarget.php by sonar-php

private methods that are never executed are dead code: unnecessary, inoperative code that should be removed. Cleaning out dead code decreases the size of the maintained codebase, making it easier to understand the program and preventing bugs from being introduced.

Noncompliant Code Example

public class Foo
{
  private function Foo() {}   // Compliant, private empty constructor intentionally used to prevent any direct instantiation of a class.

  public static function doSomething()
  {
    $foo = new Foo();
    ...
  }

  private function unusedPrivateFunction() {  // Noncompliant
  }
}

Compliant Solution

public class Foo
{
  private function Foo(){}   // Compliant, private empty constructor intentionally used to prevent any direct instantiation of a class.

  public static function doSomething()
  {
    $foo = new Foo();
  }
}

Having two cases in a switch statement or two branches in an if chain with the same implementation is at best duplicate code, and at worst a coding error. If the same logic is truly needed for both instances, then in an if chain they should be combined, or for a switch, one should fall through to the other.

Noncompliant Code Example

switch ($i) {
  case 1:
    doSomething();
    break;
  case 2:
    doSomethingDifferent();
    break;
  case 3:  // Noncompliant; duplicates case 1's implementation
    doSomething();
    break;
  default:
    doTheRest();
}

if ($a >= 0 && $a < 10) {
  doTheThing();
else if ($a >= 10 && $a < 20) {
  doTheOtherThing();
}
else if ($a >= 20 && $a < 50) {
  doTheThing();  // Noncompliant; duplicates first condition
}
else {
  doTheRest();
}

if ($b == 0) {
  doOneMoreThing();
}
else {
  doOneMoreThing(); // Noncompliant; duplicates then-branch
}

var b = a ? 12 > 4 : 4;  // Noncompliant; always results in the same value

Compliant Solution

switch ($i) {
  case 1:
  case 3:
    doSomething();
    break;
  case 2:
    doSomethingDifferent();
    break;
  default:
    doTheRest();
}

if (($a >= 0 && $a < 10) || ($a >= 20 && $a < 50)) {
  doTheThing();
else if ($a >= 10 && $a < 20) {
  doTheOtherThing();

Severity: Major
Found in src/Debug/Plugin/ConfigEvents.php by sonar-php

Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.

Noncompliant Code Example

function doSomething($a, $b) { // "$a" is unused
  return compute($b);

Compliant Solution

function doSomething($b) {
  return compute($b);
}

Exceptions

Functions in classes that override a class or implement interfaces are ignored.

class C extends B {

  function doSomething($a, $b) {     // no issue reported on $b
    compute($a);
  }

Severity: Major
Found in src/Debug/Plugin/Method/GroupCleanup.php by sonar-php

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;
