<p>I've been stuck on this problem for a while now. 
I was also given some tips on how to start off as given here;</p>

<p><strong>Hint: use a loop and the strlen() method for a string
strlen("Hello")  will yield the value 5 since Hello has 5 characters
Strings can also be treated like an array, so for instance:
$s = "Hello";
print $s[0];   // this would yield H  since H is in the 0 position of the string
Think about using a for loop that starts with the length of the string and counts backward.</strong></p>

<p>So far I've been going back and forth between the code but right now I can't even get myself to think of how to start the code.</p>

<p>Any help would be appreciated. </p>
