Extracting Unique Values from an Array?

[duckduckgoose]

I really don't know where to start here, so guidance is appreciated.

Let's say I have a series of values:

$list = "milk, bread, cheese, milk, milk, eggs";

If I explode these:

$exploded = explode("," $list);

Is there a way that I can then filter out the duplicate values, so that the resulting list will look like:

Array
(
    [0] => milk
    [1] => bread
    [2] => cheese
    [3] => eggs

)

Thanks much!

There's this function called [man]array_unique/man....

Perfect. Had no idea this existed.
