2 Different Random Data Sets

[axman505]

I will have an array of items. From this array I will need to obtain two completely different random sets of data. What is the best way to do this?

I can use array_rand to get one set .. but how do i then get a totally different set?

Thanks.

Copy the array to another variable and use array_rand() again, maybe?

but there is no guarentee that will be a completely unique set from the first set. If I needed 2 sets of 500 .. i could just run array_rand(Array, 1000) and split the array in half.

But what if i need a set of 500, and a set of 200 or something like that

Select 700 and split it 5/7 to 2/7.

Or treat your arrays like stacks.

Use array_rand() in loops to fetch a single random key each loop iteration. Use that key to push the value to your destination array and remove that value from the original array.
