php combination generator

[greenstar91]

I have recently finished a combination calculator for finding the number of combinations of a group of numbers.

http://greenstar91.007sites.com/index.php <<excuse the free hosted site!

Now I want to create a script that will list every single combination in order for a user defined character set (most likely lower case + numbers) i.e. if user types in 'abcdefghijklmnopqrstuvwxyz0123456789' and 6 combination length. I want the script to list every combination starting from aaaaaa, aaaaab, aaaaac e.t.c.

I know this is not the best language to be doing it in and akso it will take up a lot of space. i still wish to proceed as then i want to put the results into a database.

thanks

Would you be selecting the combinations from a database? or perhaps a text list?

there would be a text input box where the user inputs every character they want and when they press submit all possible combinations are generated and placed in a text file or a database on the server or available as download. space is not an issue.

I mean where is it getting the list of possible combinations, or is it working it out.

it would work it out and put results in database or other file

Whats the algorithm to work out the code? Or the method used.

I think there is a misunderstanding here.

All I need is some help with making a set group of characters go into every possible combination they can make within 6 digits. I want this to be generated into a dtabase or text file.
