[FIXED] Reverse the order of letters in the last word in a string

Issue

I am trying to reverse the final word in a string.

A multi-word string:

$string = "i like to eat apple";
// to be:  i like to eat elppa

A single word string:

$string = "orange";`
//to be:   egnaro

How can I reverse the order of letters in only the last word -- regardless of how many words are in the string?

Solution

I have been Found the answer. For my own question

$split = explode(" ", $words);
$v_last = $split[count($split)-1]; 
$reverse = strrev($v_last);
$f_word = chop($words,$v_last);
echo $f_word;
echo $reverse;
