Define a constant instead of duplicating this literal "../video/" 5 times. Open

- Exclude checks
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.
Define a constant instead of duplicating this literal "committee" 4 times. Open

Remove the unused function parameter "$message". Open
function requeue($message)
- 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); } }

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.
