RE: [PHP] stepping through alphabet

[snip] for ($letter = 'A'; $letter++; $letter <= 'Z') echo "<a href=\"?action=alphabet&letter=$letter\">$letter</a>\n"; [/snip] I tested this and found two small problems. The code works if you do this (I was myself amazed that letters would increment) for($letter = 'A'; $letter < 'Z'; $letter++){ echo $letter . "\n"; } The problem seems to be that you cannot use <='Z' for some reason, as the array becomes quite lengthy, as if 'Z' doesn't work properly. But, if I do this for($letter = 'A'; $letter < 'Z'; $letter++){ echo $letter . "\n"; } echo $letter . "\n"; The second echo statement echos the 'Z' properly.
