In other words, it's equivalent to this: print $foo; $foo = $foo + 1; not this: $foo = $foo + 1; print $foo; -- Daniel Grace -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Questions: 1. $letter++ -- why doesn't this evaluate $letter as integer before incrementing? 2. print $letter++ -- why doesn't this evaluate to b at the first loop when it's already 'a'? Ok, this I may be able to explain because it's neither print ++$letter nor print ($letter++), but I wouldn't have trusted this syntax to work this way a million years! Nice, elegant code indeed!

RE: [PHP] Re: Generate Alphabet
Sorry for the late reply but maybe you should take a look at the function
range.
from the manual:
foreach(range('a', 'z') as $letter) {
echo $letter;
}

Re: [PHP] Re: Generate Alphabet
This will only work with PHP 4.1.0 or later.
Consider this example:
$letter = 'a';
$i = 0;
while ($i++ 26) {
print Letter: . $letter++ .\n;
}

Re: [PHP] Re: Generate Alphabet
I seriously doubt your code works -- have you tested it? I think the code
you submitted will most probably output 1 2 3 4...24 25 26 (spaces are
actually \n's). I never tested it though, so I may be mistaken.
However, with just a few changes we get
$letter='a';
$i=0;
while ($letter'z') {
$letter=Chr(ord($letter)+$i);
$i++;
print($letterbr\n);
}
which should work.
