weird PHP range() issue

[Fint]

I think I'm using this function slightly wrong, but the output is really odd...

<?php
 foreach (range('a', 'Z') as $letter) {
     echo $letter;
 }
?>

But it outputs

a`_^]\[Z

Can anybody else verify this?

Yes,

Technically, you're going backwards in the list.
(take a look at the ascii table http://www.asciitable.com/)

Z comes before a in ascii, so range goes backwards in your list.

<?php
 foreach (range('A', 'z') as $letter) {
     echo $letter;
 }
?>

outputs

ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz

Ah, ok, that makes sense. I didn't figure that any of [\]^_` would be a list of a-z.

Thanks.

In Perl, I would do

@alpha=('a'..'z', 'A'..'Z');

In PHP, the best way I've found is to do

$lower=range('a','z');
$upper=range('A','Z');
$alpha=array_merge($lower,$upper);

Is there a "better" way?

x2. Is it not skipping part of the table?
