I have an array of languages that looks like this: (this data is pulled from mysql stored as: e.g. field value: greek, polish)
Array (  =>  => french  => french, greek  => german  => greek  => greek, polish  => italian  => spanish  => spanish, italian  => spanish, portuguese )
I have tried using array_unique($languages) but the output stays the same.
I assume it is because of the comma.
Any idea on how to just have unique values? e.g. one each of: french, greek, german, polish, italian, spanish, and portuguese?
