107521 Simple Fast Script Needed

Hello All, I am looking for a script that will generate variation of words for me. for example, I will tell the script, I want to have all possible 4 letters words the script will generate all words possible from a combination done between the 4 letters like aaaa aaab aaac etc until all of them are done I can also tell the script to use numbers randomly in the words I can also tell the script to use - randomly in places of the word and so on. another example would be: We would tell the script to output all the probabilities of 3 digits consisited of 2 alphabets and 1 number for example, so, it would get the lists like: aa1 a1a 1aa aa2 a2a 2aa etc... I think with any advanced PHP coder, this could be already done and ready. as you can see, this is a VERY simple script that I need ASAP Thanks
