Instead of using a regular expression, you could just create an array of values (A-J and k-t). You can then see if $checkChar is in the array with in_array(). More information about in_array() can be found here:

http://php.net/manual/en/function.in-array.php

 

Also note that you could create the array using a combination of range() and array_merge().

What's the benefit? It's literally twice as much code and arguably less readable.

 

I guess it depends on what the code is used for. When I've had code like this in the past, the array of characters is used in other parts of the script. However, you're probably right about regular expressions fitting better in this case.
