how to get top 3 values in php array and their index

Question

I want to get the highest value, the second highest value and the third highest value

For example, I have an array like:

$n = array(100,90,150,200,199,

Answer 1

Try this:

$n = array(100,90,150,200,199,155,15,186);
rsort($n);
$top3 = array_slice($n, 0, 3);
echo 'Values: ';
foreach ($top3 as $key => $val) {
 echo "$val\n";
}
echo '
';
echo 'Keys: ';
foreach ($top3 as $key => $val) {
echo "$key\n";
}

Output:

Values: 200 199 186 
Keys: 0 1 2
