[SOLVED] looping through letters

[perezf]

how can i loop through letters for instance

aaa

aab

aac

aad

 

etc...??

 

I know how to do it with numbers

but not letters

I don't see why not.

 

$letters = range('a', 'z');

 

foreach($letters as $letter) {

    echo $letter . "\n";

}

 

[perezf]

that only works for

a

b

c

d

e

f

g

etc...

 

i need

aaa

aab

aac

aad

aae

aaf

...

aba

abb

etc...

 

how can i pull that off

You can try:

<?php
$letters = range('a', 'z');
for ($first=0;$first<count($letters);$first++){ 
      $firstletter = $letters[$first];
              for ($second=0;$second<count($letters);$second++){
                        $secondletter = $letters[$second];
                                 for ($third=0;$third<count($letters);$third++) {
                                         $thirdletter = $letters[$third];
                                         echo $firstletter . $secondletter . $thirdletter . "<br />";
                                 }
               }
}
?>

 

That's what I thought up in about 30 seconds.  I mean I could probably right some recursive function that just makes a large array that you can loop through, but I'm kind of in a non-thinking state at the moment.  Btw, I just tested that code and it works. xD

Wow I cannot believe I said "right" instead of "write".  I just finished writing a letter in Greek to send to a friend and now I can't think straight. >_<  Not sure why. xD  Excuse the incorrect word from the previous post. =P
