How to count the maximum consecutive set of numbers in an array with PHP

Answer 1

function countMaxConsecutiveSetOfNumbers($arr) {
    $size = count($arr);
    
    $set = array();
    
    for ($i = 0; $i < $size; $i++) {
        (!in_array($arr[$i],$set) ?  array_unshift($set, $arr[$i]) : 0);
    }
    
    $mx = 0;
    for ($i = 0; $i < $size; $i++) {
        if (in_array($arr[$i], $set)) {
            $temp = $arr[$i];
            while (in_array($temp, $set)) {
                $temp++;
            }
            $mx = max($mx,$temp - $arr[$i]);
        }
    }

    return $mx;
}
        
$arr = array(22, 3, 21, 32, 24, 31, 4, 99, 23);
        
// 21 22 23 24

echo countMaxConsecutiveSetOfNumbers($arr);
