[SOLVED] array_unique for strings?

Hi,

 

I'm wondering if there's something similar to array_unique, but for strings?

 

For example, I have a string:

 

$ids = "23,24,25,24,24,24";

 

Is there anyway to strip the string down so that it keeps the unique numbers separated by the commas?

 

Thus, I would retrieve from the $ids above:

 

23,24,25.

 

Thanks!
