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.
Rename "$resource" which has the same name as the field declared at line 31. Open
$resource = $this->resource;
- Read upRead up
- Exclude checks
Shadowing fields with a local variable is a bad practice that reduces code readability: it makes it confusing to know whether the field or the variable is being used.
Noncompliant Code Example
class Foo { public $myField; public function doSomething() { $myField = 0; ... } }
See
- CERT, DCL51-J. - Do not shadow or obscure identifiers in subscopes

Remove or refactor this statement. Open
$absValues['declaredLast'] === $absValues['inheritedFrom'];
- Read upRead up
- Exclude checks
Any statement (other than a null statement, which means a statement containing only a semicolon ;
) which has no side effect and does
not result in a change of control flow will normally indicate a programming error, and therefore should be refactored.
Noncompliant Code Example
$a == 1; // Noncompliant; was assignment intended? $a < $b; // Noncompliant; have we forgotten to assign the result to a variable?
See
- MITRE, CWE-482 - Comparing instead of Assigning
- CERT, MSC12-CPP. - Detect and remove code that has no effect
- MISRA C:2004, 14.2 - All non-null statements shall either have at least one side-effect however executed, or cause control flow to change.

Reduce the number of returns of this function 4, down to the maximum allowed 3. Open
public static function getParentReflector(Reflector $reflector)
- 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
// xdebug < 3.0: namespace\{closure}
- Read upRead up
- Exclude checks
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.
See
- MISRA C:2004, 2.4 - Sections of code should not be "commented out".
- MISRA C++:2008, 2-7-2 - Sections of code shall not be "commented out" using C-style comments.
- MISRA C++:2008, 2-7-3 - Sections of code should not be "commented out" using C++ comments.

Remove the unused function parameter "$array2". Open
public static function diffAssocRecursive(array $array1, $array2) // phpcs:ignore Generic.CodeAnalysis.UnusedFunctionParameter
- Read upRead up
- Exclude checks
Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.
Noncompliant Code Example
function doSomething($a, $b) { // "$a" is unused return compute($b); }
Compliant Solution
function doSomething($b) { return compute($b); }
Exceptions
Functions in classes that override a class or implement interfaces are ignored.
class C extends B { function doSomething($a, $b) { // no issue reported on $b compute($a); } }
See
- MISRA C++:2008, 0-1-11 - There shall be no unused parameters (named or unnamed) in nonvirtual functions.
