So I'm really not good with math, formula's and the like. This is a little bit above my head.
I basically have an array, or a database with about 30 emoji's in it. I want to basically enter in a number into a form, lets say 3, then hit submit. the php script will then make as many unique combinations of 3 emoji's as possible, and then place them back into an array, or even just output right onto the screen separated by a new line.
I know how to code the form, i know out to output things to the screen and place items back into the array, etc etc... I have some good experience coding, but i'm not sure how to go about creating the unqiue combinations of the emoji's based upon user input.
any help is appreciated. if any clarification is needed let me know.
