Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.
|
|
|
|
=== Noncompliant code example
|
|
|
|
[source,php]
|
|
----
|
|
function doSomething($a, $b) { // "$a" is unused
|
|
return compute($b);
|
|
}
|
|
----
|
|
|
|
=== Compliant solution
|
|
|
|
[source,php]
|
|
----
|
|
function doSomething($b) {
|
|
return compute($b);
|
|
}
|
|
----
|
|
|
|
=== Exceptions
|
|
|
|
Functions in classes that override a class or implement interfaces are ignored.
|
|
|
|
[source,php]
|
|
----
|
|
class C extends B {
|
|
|
|
function doSomething($a, $b) { // no issue reported on $b
|
|
compute($a);
|
|
}
|
|
|
|
}
