PHP Gurus: What is the easiest way to generate a specified length string of random alpha characters?

Well, this code will spit stuff out per your “For example”
Not sure what alpha characters are though…

<?php
for($i = 0; $i < 5; $i++) {
     $string = ’’;
     for($j = 0; $j < 5; $j++) {
          $string .= chr(65 + rand() % 25);
     }
     echo $string.’; ’;
}
?>

Check it here.

Thanks Breefield, you legend. :)

Oh, and I meant ‘alpha’, as in ‘alphabet’.

@richardhenry, I think you’re getting what you want, but just pointing out that that example will only ever return UPPERcase chars (the chr function in PHP returns a character based on the ASCII integer value provided.) You’d need to add some more complexity to get a mix of lowercase chars and/or numerics.

Also note that @bree modulo’d with 25… because it’s counting like 0, 1, 2…, 25 to get the twenty-six unique values for each letter of the alphabet.

@rob: Yeah noticed that. It probably would have tripped me up the first time I did it had I been doing this myself.

And yeah; caps is what I need. :) Again, thanks for giving such a great example Breefield.
