How to order an array from largest to smallest and then print them

How do I order an array from largest to smallest and then print the answers.

$number = array(2, 3, 4, 3);

PHP:

How do I do this?

 

rsort($number)
foreach ($number as $val) {
     echo "$val\n";
}

Code (markup):

 

Do you know how to add the number the number is in an array, so if I had,

$number = array(2, 3, 4, 3); // 2 would be $number[0], 3 would be $number[1], etc

PHP:

how i would add 0 to 2, 1 to 3, etc?

 

If you need to keep the key the same, you need to use arsort($number).

To add $number[0] to $number[2] you just do $number[0]+$number[2] but what are you doing with the result? just displaying it or putting into another array or something else?

 

What I want to do is add 2 to $number[2]. However I want to be able to do this to as many number as there are in the array. So add the number, 4 to $number[3]. Does that make sense?

 

For each number in the array, you want to add the count to the existing number:

// existing array
array(1,2,3,4)
//new array
array(1,3,5,7)

PHP:

if so, just do something like

$array = array(1,2,3,4,5);
$newarray = array();

for ($i = 0; $i < count($array); $i++) {
   $newarray[] = $array[$i] + $i;
}

print_r($newarray);

PHP:

 

Another way of what PoPSiCLe came up with:

$ar = array(1, 2, 3, 4, 5);
$ar2 = array_map(function($a, $b){ return $a+$b;}, $ar, range(0, count($ar)-1));
print_r($ar2);
