Import Excel to mysql in php

I'm trying to make an importer in php where in the file input I select the file and import the submit button. I need to enter the full path of the file for the import to work. How can I accomplish this?

 <?php

//ini_set("display_errors",0);
require_once 'excel_reader2.php';
require_once 'Class.BD.Mysqli.php';
//require_once './PHPExcel/IOFactory.php';




$db = new MysqliDB();
$db->conn();


$data = new Spreadsheet_Excel_Reader("path of file");

echo "Total Sheets in this xls file: ".count($data->sheets)."<br/><br/>";

$html="<table border='1'>";
for($i=0;$i<count($data->sheets);$i++) // Loop to get all sheets in a file.
{   
    if(count($data->sheets[$i]['cells'])>0) // checking sheet not empty
    {
        echo "Sheet $i:<br /><br />Total rows in sheet $i  ".count($data->sheets[$i]['cells'])."<br />";
        for($j=1;$j<=count($data->sheets[$i]['cells']);$j++) // loop used to get each row of the sheet
        { 
            $html.="<tr>";
            for($k=1;$k<=count($data->sheets[$i]['cells'][$j]);$k++) // This loop is created to get data in a table format.
            {
                $html.="<td>";
                $html.=$data->sheets[$i]['cells'][$j][$k];
                $html.="</td>";
            }
