How To Import Large Excel File To MySql Database Using PHP

Can anyone please tell me that how can I increase the max file size limit for the code mentioned in below link:

function uploadFile($fieldName, $fileType, $folderName, $name = "")

    $ext = "";
    $uploadfile = "";
    if (isset($fieldName) AND $fieldName['name'] != '')
    {
        $flg = 1;
        $allowed_filetypes = $fileType;
        // I Need to increase this..... I tried changing values but nothing happened
        $max_filesize = 1048576;     
        $filename = $fieldName['name'];
        if ($name == "")
            $MaxID = time() . time() . rand(1, 100);
        else
            $MaxID = $name;
        $ext = substr($filename, strpos($filename, '.'), strlen($filename) - 1);
        if($ext==".xlsx")
            $ext=".xls";
        if (!in_array($ext, $allowed_filetypes))

        for($i=1;$i<=$data->sheets[0]['numRows'];$i++)
        {
            $firstname=$data->sheets[0]['cells'][$i][1];
            $lastname=$data->sheets[0]['cells'][$i][2];

            $city=$data->sheets[0]['cells'][$i][4];
            $query="INSERT INTO StudentData(FirstName,LastName,MobileNo,City)VALUES('".$firstname."','".$lastname."','".$mobile."','".$city."')";
            mysql_query($query);
        }
    }
}
if(isset($_POST['delete']))
{
    mysql_query("DELETE FROM StudentData");
}
?>

Solution

According to ASNAOUI Ayoub I made the following changes:

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

But Stil the Problem was same then I tried to change the

$max_filesize = 41943040

Now It perfectly works.....

Thanks Everyone for the help
