array multidimensionale e indici

[leonapster]

Questo è l'array

Array
(
    [0] => Array
        (
            [id] => 1
            [season_id] => 1
            [treatment_type] => 1
            [room_id] => 1
            [base_price] => 120
        )

    [1] => Array
        (
            [id] => 2
            [season_id] => 1
            [treatment_type] => 1
            [room_id] => 2
            [base_price] => 140
        )

    [2] => Array
        (
            [id] => 3
            [season_id] => 1
            [treatment_type] => 1
            [room_id] => 3
            [base_price] => 160
        )

    [3] => Array
        (
            [id] => 4
            [season_id] => 1
            [treatment_type] => 1
            [room_id] => 4
            [base_price] => 180
        )

    [4] => Array
        (
            [id] => 5
            [season_id] => 1
            [treatment_type] => 1
            [room_id] => 5
            [base_price] => 200
        )

    [5] => Array
        (
            [id] => 21
            [season_id] => 2
            [treatment_type] => 1
            [room_id] => 1
            [base_price] => 120
        )

) 

Devo stampare il valore 'base_price' dell'array con seasons_id = 2 and treatment_type = 1 and room_id = 1
