How to sort array numbers high to low in PHP?

Question

It is array:

$a = rand(1,100);
$b = rand(1,100);
$c = rand(1,100);
$arr =  array($a ,$b , $c);

I want to sort generated numbers high to low.

I've downvoted for the begging in the title - we try to discourage that sort of behaviour here. — halfer, Aug 31 '16 at 19:24

It's simple:

rsort($arr);

Sort Array (Descending Order), According to Value - arsort()

<!DOCTYPE html>
<html>
<body>

<?php
$age = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
arsort($age);

foreach($age as $x => $x_value) {
    echo "Key=" . $x . ", Value=" . $x_value;
    echo "<br>";
}
?>

</body>
</html>

Output:

Key=Joe, Value=43
Key=Ben, Value=37
Key=Peter, Value=35

Use arsort(): reference

    print_r(arsort($arr));
