    {
        $Filepath = $argv[1];
    }
    elseif (isset($_POST['File']))
    {
        $Filepath = $_POST['File'];
    }
    else
    {
        if (php_sapi_name() == 'cli')
        {
            echo 'Please specify filename as the first argument'.PHP_EOL;
        }
        else
        {
            echo 'Please specify filename as a HTTP GET parameter "File", e.g., "/test.php?File=test.xlsx"';
        }
        exit;
    }

    // Excel reader from http://code.google.com/p/php-excel-reader/
    require('php-excel-reader/excel_reader2.php');
    require('SpreadsheetReader.php');

    date_default_timezone_set('UTC');

    $StartMem = memory_get_usage();


    try
    {
        $Spreadsheet = new SpreadsheetReader($Filepath);
        $BaseMem = memory_get_usage();

        $Sheets = $Spreadsheet -> Sheets();


        //print_r($Sheets);
        $TabloArray=array();
        $Satir=array();

        foreach ($Sheets as $Index => $Name)
        {


            $Time = microtime(true);

            $Spreadsheet -> ChangeSheet($Index);

            foreach ($Spreadsheet as $Key => $Row)
            {
                //echo $Key.': ';
                if($Key==0)
                {


                    continue;
                }
                if ($Row)
                {
                    $Satir['Isim']=$Row[0];
                    $Satir['SoyIsim']=$Row[1];
                    $Satir['Yas']=$Row[2];
                    $TabloArray[]=$Satir;
                }
                else
                {
                    var_dump($Row);
                }
                $CurrentMem = memory_get_usage();
            }



        }
        print_r(json_encode($TabloArray));

    }
    catch (Exception $E)
    {
        echo $E -> getMessage();
    }

And JavaScript code for read

json_obj = $.parseJSON(veri);//parse JSON
for(var i in json_obj)
    {
        Isimler[i]=json_obj.Isim;
        SoyIsim[i]=json_obj.SoyIsim;
        Yas[i]=json_obj.Yas;
        var Table=document.getElementById("tablo_icin2");
        var td = document.createElement("td");
        var tr=document.createElement("tr");
td.appendChild(document.createTextNode(json_obj[i].Isim));
                tr.setAttribute("id","element"+i);
                tr.appendChild(td);
                td = document.createElement("td");
td.appendChild(document.createTextNode(json_obj[i].SoyIsim));
                tr.appendChild(td);
                td = document.createElement("td");
td.appendChild(document.createTextNode(json_obj[i].Yas));
                tr.appendChild(td);
                Table.appendChild(tr);
}

Answer 1

Use parser: If you want read file by JavaScript you can use https://github.com/SheetJS/js-xlsx for it. It you want read file by php you can use https://github.com/PHPOffice/PHPExcel/tree/develop/Documentation after upload you file as simple file.

Answer 2

Why not just upload the file to the server and save its path to the database. And then when you want to read it, fetch the path from database relative to the upload folder of the excel file.
