[PHP] Tabela Array

Mam tebelę:
Array
(
[pwi_nl100] => Array
(
[0] => n
[1] => y
[2] => 100
[3] => y
[4] => x
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
[10] => 4000
[11] => n
[12] => 4
[13] => 4
[14] => default
)

[pwi_nl50] => Array
    (
        [0] => n
        [1] => y
        [2] => 50
        [3] => y
        [4] => x
        [5] => 0
        [6] => 0
        [7] => 0
        [8] => 0
        [9] => 0
        [10] => 2000
        [11] => n
        [12] => 2
        [13] => 2
        [14] => default
    )

[qsyifi_ifi 150] => Array
    (
        [0] => n
        [1] => y
        [2] => 150
        [3] => y
        [4] => x
        [5] => 5
        [6] => 5
        [7] => 15
        [8] => 1
        [9] => 5
        [10] => 4000
        [11] => n
        [12] => 3
        [13] => 3
        [14] => default
    )

)
