How is it possible to retrieve the last character of a string?

I want to be able to find out the last character of a string, and if it is a certain character do something (obviously i know this will be through an if statement).

I figured out how to break the string into an array, but then using that array how do i get the last character?

Thanks

PHP Code:

$char = substr($string, -1); // returns the last character of  $string 


Reference

If you use frost's example above, you won't need to break the string into an array. But to answer another question you have, you can access the last element of an array by using:

echo end($array);

$char = $string[strlen($string)-1]; // you can refer to a string as to array without breaking

Thanks all
