This may not be the best way but you can do it this way: 1. Make sure that the number 1 above is in an array. Then, 2. Make an array of uppercase and lowercase letters, shuffle() them. 3. Get 12 from each. (i.e. by looping thru each and assigning it to another array, etc.) 4. array_merge() the two resulting arrays. 5. shuffle() again.
