Converting Multi Index Excel file to array in PHP

I have used maatwebsite/excel 2.1 to read the excel file but i faced problem while reading multiple heading excel file(EX: as shown in first fig). I can't read all the data as it skipped all the rows except first of second heading(As shown in second fig highlighted).

First Image with excel data

Second Image with only fetched data highlighted

The data was fetched as:

[
    {"name":"First","0":"F","address":"Country","result":"A"}, 
    {"name":"foo","0":456,"address":"nep","result":324}, 
    {"name":"bar","0":456,"address":"aus","result":324}, 
    {"name":"baz","0":222,"address":"uk","result":21}
    ]

Skipping all the other row of data. So, i want ask for help in fetching all data and also in organised way if possible EX:

["name":{
            "first":"foo",
            "middle":" ",
            "last":"asd"
           },
  "address":{
             "country":"nep",
               ...
               ],
 ...
]

OR AS

[{
   "name.first":"foo",
   "name.middle":" ",
   "name.last":"asd",
   "address.country":"nep",
    ......}]

If this is not possible with available library than can anyone tell me how the excel individual cell data is read in PHP(core level).
