Using WWWForm to post an array of data

I need to post an array of Data for a php script to act upon it, any tips on how i would do this

I’d suggest CSVs in a text field.

That might work, could be my only option , although I could explode() the array, then in PHP turn it back into an array, and when getting it back, explode the same array, print it out and run a get www.text
