This isn't the place for questions. Something like the following
should work. I haven't tested it.
<?php
$ind = mt_rand(0, 25);
$alphabet = 'abcdefghijklmnopqrstuvwxyz';
$my_random_char = $alphabet[$ind];
?>
In the future, please use the mailing lists for coding questions.

I would like to be able to create a random letter from A-Z for a member login authorization code. I
would like to have a 7 digit number ie: A543BC21 so that they can create a username and password. I
know how to randomize a number (ie: mt_rand( 0, 9 );) but how can I randomize letters? I tried
using mt_rand( "A", "Z" ) but as I expected, it gave me an "Invalid
Range" error. I could do this:
<?
$letter = mt_rand( 1, 36 );
if( $letter == "1" )
{
$letter = "A";
}
//etc. like this for A-Z
?>
but it would be exceptionally messy and way too long. Is there any other way to do it? If it
doesn't exist, can you add this to the next version of PHP?
Thanks so much!
