How can the Gruppenbruchverfahren method be adapted to group array values that are consecutive in PHP?

When using the Gruppenbruchverfahren method to group consecutive array values in PHP, we can iterate through the array and compare each value with the previous one. If the values are consecutive, we can group them together. One way to implement this is by using a loop to iterate through the array and checking if the current value is one greater than the previous value. If it is, we can add it to the current group; if not, we can start a new group. 

$array = [1, 2, 3, 5, 6, 7, 9, 10, 11];

$groups = [];
$currentGroup = [];

foreach ($array as $key => $value) {
    if ($key > 0 && $value == $array[$key - 1] + 1) {
        $currentGroup[] = $value;
    } else {
        if (!empty($currentGroup)) {
            $groups[] = $currentGroup;
        }
        $currentGroup = [$value];
    }
}

if (!empty($currentGroup)) {
    $groups[] = $currentGroup;
}

print_r($groups);
