PHP unique array after merge

Question

Is there a better way to achieve the following:

array_unique(array_merge($array_one, $array_two))

That is, merge two arrays and only have unique values.

array_merge seems to merge uniquely for keys, but i need unique values and can not see a built in function that does this.

I understand 'better' may be subjective. Im thinking purely in the fact that im using two array functions wraped to get the values.

Not sure you can do it in one fail swoop - two functions isn't bad though .. the only other suggestion is to slip in a condition when forming the second array ($array_two - or the last array formed), e.g.

for($i=0; $i<10; $i++) {
   $array_one[] = $i;
}

for($k=5; $k<15; $k++) {
   if(!in_array($k,$array_one)) $array_two[] = $k;
}

Although of course if the first array isn't fully formed (finished) before the second array begins then this won't help. And if it takes too much delving to do this I would consider keeping the original - as long as it does what you want_g
