Convert php String to int array and sort

I have this string in php.

$string = "17,3,25,29,35,81,40,45,50";

I need to explode it to an integer array and sort it in ascending order.

I used this code but that is not working.

$myArray = array_map('intval', explode(',', $string));
$sortedArray = sort($myArray);
print_r($sortedArray);

What is the error?

$string = "17,3,25,29,35,81,40,45,50";
$array = array_filter(array_map('trim', explode(',', $string)));
asort($array);
$array = implode(', ', $array);
print_r($array);

sort function doesn't return a sorted array, it sorts an argument array by reference. What you need to do is:

$myArray = array_map('intval', explode(',', $string));
sort($myArray);
print_r($myArray);

<?php 

$string = "17,3,25,29,35,81,40,45,50";
$myArray = explode(',', $string);
sort($myArray);
print_r($myArray);// to print array

echo $newstring =implode(',',$myArray);
