I'm importing excel file with Laravel PHPExcel, it works fine, but I need to get just the first cell of each row which is telephone column, this is my code,

public function importar()
{ 
    $path = 'public/excel/excelinvitaciones.xlsx';
    Excel::filter('chunk')->load($path)->chunk(250, function($results)  
    {
            $invitacion = new PuertoInvitacion();
           
            for ($i=0; $i <= count($results); $i++) 
            {  
                   
                $arrayInvitacion = ["idpuerto" => "1" , "telefono" =>  $results[$i][0]];
                $invitacion->crearNueva($arrayInvitacion);  
                
            } 
    }); 
} 

the Excel file looks like this

A1         
   416723123  
   414123723  
   412123123

It's just saving [414123723]

id   idpuerto  telefono  
1      1         [414123723]

I'm new at this, I can't understand how I have to handle $results to get just that cell information, thank you.
