Unused parameter false positive when using array index in arrow function

[ghnp5]

Hello,

This works fine:

$found = in_array_cb($needle, $haystack, function($array, $needle) {
	return $array[2] === $needle;
});

But in the bellow, PHPCS complains with "The method parameter $needle is never used" (Generic.CodeAnalysis.UnusedFunctionParameter.FoundAfterLastUsed):

$found = in_array_cb($needle, $haystack, fn($array, $needle) => $array[2] === $needle);

If I remove "[2]", PHPCS does not complain:

$found = in_array_cb($needle, $haystack, fn($array, $needle) => $array === $needle);

Looks like this is caused by the T_FN end token matching, and something in the sniff itself. I've fixed the T_FN end token but still confirming that, and looking into the sniff.

I've pushed a fix for this now. Thanks for reporting it.
