PHP Incremental Alphabets

12 Apr

Ever have a case where you want to increment alphabets in PHP?

E.g.

AAA
AAB
….
AAZ
ABA
ABB

Apparently in PHP, you can do it very easily.

$x = 'AAZ';
$x++;
echo $x; //will output ABA

Though strangely decrementing it ($x–) won’t work.

Credits to this site for pointing this little tidbit out.
