Sending array of data to PHP at server from vb.Net

I don't know if this is even possible, and I can't figure how to achieve this.

I have 50 (can be more) records in MS Access database that I wish to send to a a php file at my server for further processing.

What I have implemented so far is that I loop through the records and send them one by one. This kind of takes time cause of network issues, some records will be sent and others won't and each data sent will have to wait for report from server before the next one will be sent.

Is there a way I can send all records once, maybe in an array or something and be able to access it at the server side?

Below is my table schema.

--------------------------
|  id  |  phone  |  msg  |
--------------------------
|  1   | 09023023|  hi   |
|  2   | 09023024|  hey  |
|  3   | 09023025|  dear |  
--------------------------

Thanks

I found a solution for this. I don't know if it is the best way out there but it worked well.

On @Tushar Gupta suggestion, I created a Json Array using a third party Json Library found at http://www.newtonsoft.com/

I looped through the data in the database and concatenated them like so:

CODE

    Dim sms As New Sms 'note that this is a class
    Dim sms_obj As String = ""


    Try
        conn.Open()

        Dim cmd As OleDbCommand = New OleDbCommand("id, phone, msg FROM sms;", conn)

        Dim reader As OleDbDataReader = cmd.ExecuteReader


        'collate sms
        Dim i As Integer = 0
        While reader.Read()

            sms.id = reader("id").ToString()
            sms.member_phone = reader("phone").ToString()
            sms.member_message = reader("msg").ToString()


            If sms_obj = "" Then
                sms_obj = sms_obj + JsonConvert.SerializeObject(sms, Formatting.Indented)
            Else
                sms_obj = sms_obj + "," + JsonConvert.SerializeObject(sms, Formatting.Indented)
            End If

        End While

        sms_obj = "{ ""sms""" + ":" + "[" + sms_obj + "]}" ' this put the json string in an array

        'close the connection
        conn.Close()


        If sms.ToString <> "" Then
            HelperModule.SendSms(sms_obj)
        End If


        lblSmsState.Text = "sending sms done!"

    Catch ex As Exception
        msgbox(ex.toString())
        conn.Close()
    End Try

OUTPUT

    { "sms":[
          {
            "id": "1",
            "member_phone": "09023023",
            "member_message": "hi"
          },{
            "id": "2",
            "member_phone": "09023024",
            "member_message": "hey"
          },{
            "id": "3",
            "member-phone": "09023025",
            "member_message": "dear"
          }

        ]
      }
