I have code that opens a CSV file and loops through every row of data and creates a table from it.

There are specific columns I'd like to ignore. How do I change my code to not display certain columns?

```
    <?php
    echo "<table>\n\n";
    $f = fopen("users.csv", "r");
    while (($line = fgetcsv($f)) !== false) {
            echo "<tr>";
            foreach ($line as $cell) {
                    echo "<td>" . htmlspecialchars($cell) . "</td>";
            }
            echo "</tr>\n";
    }
    fclose($f);
    echo "\n</table>";

```
