Hi,
just for fun I tried the following code:
<code>
for($letter = 'A'; $letter <= 'Z'; ++$letter) {
echo($letter . ' ');
}
</code>
What surprised me was the output, which looked like this:
A B C [] Y Z AA AB AC [] YY YZ
I don't have any idea how these letters get printed out, so I'd
appreciate any guesses or explanations.
thanks,
Norbert

Read the manual and search the archives, this was beaten to a bloody
pulp several months ago. (Hint: this DESN'T work like ascii in C).

Cheers,

This was discussed a lot a couple months back (Rasmus answered it about
20 times). This is my rendition.

When you increment a string, you get:

'A' + 1 is 'B'

'Z' + 1 is 'AA'

Because of how string comparisons go, 'AA' is greater than 'Z' (strings
are compared letter by letter), so the loop won't terminate at 'Z', like
you'd expect.

This topic was discussed at quite some length before, and Rasmus helped us all
understand it. The reason that happens is the next "letter" after Z is AZ,
which alphabetically is less than Z. You could change your statement to use
$letter < 'AZ'. I think that would work.

Thanks for all your replies and sorry about asking a question answered
in the manual. I was too surprised of the result, so I didn't even think
I could find that topic in the manual. Sorry.
