random number

[babaz]

i wanted to choose 5 random numbers from 0-20. each number represents an index in an array. is there a way to pick out 5 random items from the array. say if random number generator piked a number 22, the last item in the array is at index 20, it wud then have to go to index 0.

 

thanks!

Sorry? rand has min & max arguments.

You might also like to use array_rand which fetches a specified number of random keys from an array.

For picking more than one when duplicates aren't allowed (which you said nothing about but I would still guess so), I prefer shuffle and array_slice.
