Hi, I have a problem I don't know how to get it to work the best way.

I need to loop trough an array like the one below. I need to check if the [country] index is equal to a Spanish speaking country (lot of countries) and then get those [title] indexes of the correspondent country and check for duplicates.

The original array:

Array
(
    [0] => Array
        (
            [title] => Jeux de pouvoir 
            [country] => France
        )

    [1] => Array
        (
            [title] => Los secretos del poder
            [country] => Argentina
        )

    [2] => Array
        (
            [title] => Los secretos del poder 
            [country] => Mexico
        )

    [3] => Array
        (
            [title] => El poder secreto 
            [country] => Uruguay
        )
)

To help you understand, the final result I need to get looks something like this:

Array (
    [0] => Array
        (
            [title] => Los secretos del poder
            [country] => Argetnina, Mexico
        )
    [1] => Array
        (
            [title] => El poder secreto
            [country] => Uruguay
        ) )
