[RESOLVED] strip duplicate values in string

[zzz]

I have a string of numbers, separated by comma. How do I strip duplicate values in a string? Do i need to convert it to array to do that and then back to the string?

1339,41,1909,1339,41,1909

That is what I would do.

[devinemke]

$string = '1339,41,1909,1339,41,1909';
$array = explode(',', $string);
$array = array_unique($array);
$string = implode(',', $array);

echo $string;

Great, thanks!
