Picking random number from int array

I have an array of int values ie. 5,20,32,79,98,etc...

How would I go about randomly selecting one of those values?

I know rand(min,max) can select a randmon number between 2 given values, but I need to only pick a number that is in the array.

Thanks!😃

Obviously, a solution is to use rand(0, count($array)-1) to get a key for use in the array.

Better still, directly use [man]array_rand/man to get the key instead.

Ahh yah....I knew that now that you point it out. I just lost my train of thought and got lost there for a minute.

Thanks.

BTW, I am assuiming that in PHP the rand() function is already pre-seeded? Or do I need to come up with a seed first?

From PHP 4.2.x onwards, PHP's pseudo-random number generators are automatically seeded.
