Konversi data dari MS EXCEL 2007 ke Array

dalam excel ada banyak sheet, dan nantinya semua data akan di masukkan ke database mySQL.
pertama saya tampilkan array dengan print_r
hasilnya seperti dibawah





Array
(
    [1] => Array
        (
            [A] => NO. URUT
            [B] => NOMOR PEMILIH
            [C] => NAMA PEMILIH
            [D] => TEMPAT LAHIR
            [E] => TANGGAL LAHIR
            [F] => UMUR
/ USIA
            [G] => STATUS PERKAWINAN (B/S/P)
            [H] => JENIS KELAMIN
            [I] =>
            [J] => ALAMAT
            [K] => KETERANGAN
        )

    [2] => Array
        (
            [A] =>
            [B] =>
            [C] =>
            [D] =>
            [E] =>
            [F] =>
            [G] =>
            [H] => Lk
            [I] => Pr
            [J] =>
            [K] =>
        )

    [3] => Array
        (
            [A] => 1
            [B] => 2
            [C] => 3
            [D] => 4
            [E] => 5
            [F] => 6
            [G] => 7
            [H] => 8
            [I] =>
            [J] => 9
            [K] => 10
        )

    [4] => Array
        (
            [A] => 1
            [B] => 6.10101250376E+15
            [C] => SUMARWAN, AMD. KL
            [D] => SAMBAS
            [E] => 25-03-1976
            [F] => 36
            [G] => S
            [H] => Lk
            [I] => -
            [J] => DUSUN KAUM, Rw 001, Rt 001
            [K] =>

lalu kodenya ini
