PHP Array: join each sub-array together (Probability)

Question

I want simply to find-out better way to do this:

$array = array(
    array(\'a\', \'b\', \'c\'),
    array(\'e\', \'f\', \'g\'),
    array(\'h\', \'i\', \'j\'         


        

Answer 1

My non-recursive way:

 $c) {
        echo $array[$key][$c];
    }
    echo PHP_EOL;
} while (incrementCounter($counterArray, $upperBounds));

function incrementCounter(&$counterArray, $upperBounds)
{
    if (count($counterArray) == 0 || count($counterArray) != count($upperBounds)) {
        return false;
    }
    $counterArray[0]++;
    foreach ($counterArray as $key => $value) {
        if ($counterArray[$key] >= $upperBounds[$key]) {
            $counterArray[$key] = 0;
            if (isset($counterArray[$key+1])) {
                $counterArray[$key+1]++;
            }
            else {
                $counterArray[$key+1] = 1;
                return false;
            }
        }
        else {
            break;
        }
    }
    return true;
}
