1 Sort Characters in Ascending Order

In this example,

We create a string named $str.
We use the str_split() function to split the string into an array of characters.
We use the sort() function to sort the array of characters in ascending order.
We use the implode() function to join the sorted array of characters back into a string.
Finally, we print the sorted string in ascending order.

PHP Program

<?php 
$str = 'hello world';
$chars = str_split($str);
sort($chars);
$sortedString = implode('', $chars);
echo 'Sorted string in ascending order: ' . $sortedString;
?>

We use the str_split() function to split the string into an array of characters.
We use the rsort() function to sort the array of characters in descending order.
We use the implode() function to join the sorted array of characters back into a string.
Finally, we print the sorted string in descending order.

PHP Program

<?php 
$str = 'hello world';
$chars = str_split($str);
rsort($chars);
$sortedString = implode('', $chars);
echo 'Sorted string in descending order: ' . $sortedString;
