如何减少给定PHP代码段中的缩进级别

Question

How to refactor this snippet of code, to reduce indentation level by one? I just wonder is it possible in PHP to write this code in a diffrent way, with just one level of indentation.

The code:

private function isArrayMatchingCriteria(array $array) {
    foreach($array as $element) {
        if (! $this->isElementMatchingCriteria($element) {
            return false;
        }
    }
    return true;
}

Please take into consideration, that:

• this code doesn't always iterate over all array elements - so combination of count + array_filter / array_map isn't the same
• it is easy to do by introducing a dedicated object attribute serving as a flag, but I'm looking for a way without introducing new attributes

If you're just looking to remove indentation, you could use:

private function isArrayMatchingCriteria(array $array) {
    foreach($array as $element) {
        if (!$this->isElementMatchingCriteria($element)) return false;
    }
    return true;
}
