[PHP] Getting any possible value inside an array

[Aaron Bennett]

Hi everyone...

Does someone have a quick and dirty way of returning _any_ possible value
contained within an array?

For instance:

$myarray[0] = "red";
$myarray[1] = "red";
$myarray[2] = "red";
$myarray[3] = "blue";
$myarray[4] = "green";
$myarray[5] = "blue";
$myarray[6] = "red";

and i'd output "red", "blue" and "green", but not have multiple instances of
each.

Thanks in advance!
