For the purposes of outputing the alphabet,
<?php
for ($i="A"; $i <= "Z"; $i++) echo "$i<br>";
?>
will actually output A-Z, then begin again with AA, AB, etc. until it finishes with YZ. Similarly,
<?php
for ($i="A"; $i <= "ZZ"; $i++) echo "$i<br>";
?>
will output A-Z, AA, AB... ZZ, then begin again with AAA, AAB, AAC... up to ZYZ.
Thus an alternative to timrosseel's example for outputting the alphabet is:
<?php
for ($i="A"; $i != "AA"; $i++) echo "$i<br>";
?>
