Alphabetizing a word

[Mido]

How can I sort a string alphabetically? I thought about creating an array ('a'=>0, 'b'=>1) etc, but didn't manage to work. So how can I do this? is there a predefined function for this? or I should create the algorithm? Thanks,

 

Example:

$word = 'cbad432'; // should become: '234abcd'

Hi,

 

E.g. try to use the ord function to get the ASCII value of a character.

You were on the right lines.

<?php
$word = str_split('cbad432');
sort($word);
$word = implode($word);
print $word;
?>
