Tell if an array has duplicate values or not

[dombili]

I simply want to generate an array of random numbers and I also want to have no more than one instance of any numbers.

What I am thinking is having a a loop to fill in the array with random numbers and then checking the elements to see if there are any duplicates and if there are any, generating a new set.

My search led me to

array_count_values()

. It looks like I can use it and check if any of the result array elements has a value bigger than 1.

Is there a simpler way or a function for this check? (I just need to know if there are duplicates in an array or not, no removes, no replaces and such)

Thanks in advance

The above links may be what you want :)

I figured with the second one you could have a loop - comparing the previous original array with a new array (old array + new value) - if a count of both is identicle you would of had a duplicate value.

The first one will just kill off any duplicate values.

Thanks.

Yeah, looks like there are only work-arounds like that. I just wanted to make sure if I was missing a really basic function for it.
