RE: [PHP] stepping through alphabet

[Steve Buehler]

Yes, I found that the loop was written kind of backwards and would create a 
never ending loop.  I never thought to try setting $letter='A' before.  I 
didn't think you could loop through the Alphabet like that.  But I did a 
little changing to your loop and it works fine like this now:
        $letter='A';
        for($i=0;$i<=25;$i++){
                echo $letter++." ";
        }

Thank You So Much

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.
