Why Laravel-Excel reads first row as column name

I need to read an .xls file and put it into an array. I'm using laravel-excel package for reading excel files.

I have a Excel file like this :

I need to have an array like this :

[
 '9921234567' => 'First Text',
 '9929876544' => 'Second Text',
 '9927654321' => 'Third Text',
 '9928765432' => 'Fourth Text',

]

What I have tried so far :

 Excel::load('sample.xls', function($reader) {
     $reader->dd();
 });

Problem:

The problem is it reads the first row as column!

0 => RowCollection {#619
      #title: "Sheet1"
      #items: array:3 [
        0 => CellCollection {#623
          #title: null
          #items: array:2 [
            9921234567 => 9929876544.0
            "first_text" => "Second Text"
          ]
        }
        1 => CellCollection {#624
          #title: null
          #items: array:2 [
            9921234567 => 9927654321.0
            "first_text" => "Third Text"
          ]
        }
        2 => CellCollection {#625
          #title: null
          #items: array:2 [
            9921234567 => 9928765432.0
            "first_text" => "Fourth Text"
          ]
        }
      ]
    }

Look, I don't want to first row values count as column name!

Any helps would be great appreciated.
