Programmers should not comment out code as it bloats programs and reduces readability.
Unused code should be deleted and can be retrieved from source control history if required.

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.

Reduce the number of returns of this function 5, down to the maximum allowed 3. Open
public function findIndexNearDistance($targetDistance)
- 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; }
Remove this commented out code. Open
// $statement = $this->pdo->prepare("SELECT DISTINCT weathermap_maps.* FROM weathermap_auth,weathermap_maps WHERE weathermap_maps.id=weathermap_auth.mapid AND active='on' AND (userid=? OR userid=0) ORDER BY sortorder, id");

Refactor this function to reduce its Cognitive Complexity from 52 to the 15 allowed. Open
public function moveNode($nodeName, $newX, $newY)

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.

Remove the unused function parameter "$fullcommand". Open
private function handleKEYSTYLE($fullcommand, $args, $matches)
- Read upRead up
- Exclude checks
Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.
Noncompliant Code Example
function doSomething($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.
