Question

I’m using the following to discover the largest integer from 3 values.

<?php
$a = 100;
$b = 200;
$c = -300;
$max = max($a,$b,$c);
foreach( array('a','b','c') as $v) {
    if ($$v == $max) {
        echo "\$$v is $max and therefore the largest";
        break;
    }
}
?>

This works perfectly with the output: $b is 200 and therefore the largest

However, I would now like to also output the 2 smallest integers from the 3.

So as well as showing the 1 largest, it would also output the 2 others.

Can someone show me how I can achieve this?

Many thanks for any pointers.

To illustrate Matt answer :

$list = array(2, 3, 1);
sort($list);

echo "Largest element : ".$list[count($list)-1]."\n";
echo "Two smallest elements :";

for($i=0; $i<2; $i++) {
    echo $list[$i]." ";
}
