I am new to PHP and I am stuck with this problem.

$mimes = array('application/vnd.ms-excel','text/plain','text/csv','text/tsv');
if (((in_array($_FILES['uploadedfile']['type'],$mimes)))
    && ($_FILES["uploadedfile"]["size"] > 0))
{
    $filename = $_SESSION['username'].$_FILES["uploadedfile"]["name"];
    move_uploaded_file($_FILES["uploadedfile"]["tmp_name"],"./uploads/".$filename);

    echo "Stored in: " . "./uploads/" .$filename;
    echo "<br />\n";
    echo 'Daylight hours will be calculated for this latitude : '.$_POST['latCSV'];
    echo "<br>";
    //print out uploaded file.csv
    echo "<table BORDER=1>\n\n";
    echo "  <tr><th>AvgCrown</th><th>MinCrown</th><th>MaxCrown</th><th>dateLogged</th><th>DaylightHours</th></tr>";
    echo "<tbody id='tblBdyLoggedData'>";
    $f = fopen("./uploads/" .$filename, "r");
    $i=0;   //just a counter
    while (($line = fgetcsv($f)) !== false) {
        echo "<tr>";
        foreach ($line as $cell) {
            // Save the value before you output
            $lastColValue = htmlspecialchars($cell);
            //unset($lastColValue[3]);
            echo "<td>" . $lastColValue . "</td>";

        }
        //checking if date is valid
        checkDateString($lastColValue);

        // If you want to store all log dates in an array:
        $logDates[] = $lastColValue;                            
        $firstlogDate = $logDates[$i];
        echo "<td>" . checkDateString($lastColValue) . "</td>";
        //call function using firstlogDate for every row
        echo "<td>" . calcDaylight($firstlogDate,$_POST["latCSV"]) . "            </td>";
        echo "</tr>\n";
        $i = $i+1;
    }
    fclose($f);
    echo "</tbody></table></body></html>";
}

I would like to get print only the first 3 columns of the CSV file upon file upload as the two other will be calculated using respective functions. Datelogged will be taken from the csv and reformated properly and daylight Hours is also calculated from datelogged.

            if($count<3)
            {    
                echo "<td>" . htmlspecialchars($cell) . "</td>";
