$arrray1 = array(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,v,u,w,x,y,z);
$array2 = array(0,1,2,3,4,5,6,7,8,9);

What do you mean by word list? Those arrays provide every letter of the English alphabet, so why not just use a dictionary?

like all the possibilities

There are infinite combinations....

Not infinite, but a whole lot depending on your word size. For example a 3 letter word would have 17576 combinations, a 4 letter word would have 456976 combinations, etc... Luckily, this is something that computers are good at.

This will get you all 4 letter combinations of letters a-z

<?php

$alphabet = 'abcdefghijklmnopqrstuvwxyz';

$alph = str_split($alphabet);
foreach($alph as $letter1){
  foreach($alph as $letter2){
    foreach($alph as $letter3){
      foreach ($alph as $letter4){
        echo $letter1.$letter2.$letter3.$letter4.'<br />';        
      }
    }
  }
}
?>

if you need numbers and letters use

$alphabet = 'abcdefghijklmnopqrstuvwxyz0123456789';

Infinite given no word size. Just multiply infinity by 26 to get the number of combinations with one more letter!

But since the longest (English) word in the world is PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS
we can safely say that the word size is going to be 45 or less characters, which is just short of infinity

(I think you meant to say 26^infinity?)
