Deleting repeats out of an array

[Anon]

How can I sort through an array of strings and delete any repeats?

Thanks

Just an example from PHP documentation:

$input = array ("a" => "green", "red", "b" => "green", "blue", "red");
$result = array_unique ($input);

$result now contains only unique values array ("a" => "green", "red", "blue");

then you are able sort the array with function sort:

sort($result);
