How to print the top 3 largest values from array in PHP

Answer 1

function printTop3($arr) {
    $len = count($arr);

    if ($len < 3) {
        return;
    }
 
    $first = $second = $third = PHP_INT_MIN;
    for ($i = 0; $i < $len ; $i++) {
        if ($arr[$i] > $first) {
            $third = $second;
            $second = $first;
            $first = $arr[$i];
        }
        else if ($arr[$i] > $second) {
            $third = $second;
            $second = $arr[$i];
        }
        else if ($arr[$i] > $third)
            $third = $arr[$i];
    }
 
    echo $first, " ", $second, " ", $third;
}
 
 
$arr = array(12, 98, 80, 50, 88, 35, 70, 60, 97, 85, 89);

printTop3($arr);




/*
run:
