php - Read CSV into HTML table - ignore specific columns -

i have code opens csv file , loops through every row of data , creates table it.

there specific columns i'd ignore. how change code not display columns?

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

if base on indexes of column, example :

<?php     echo "<table>\n\n";     $f = fopen("users.csv", "r");     $idscolumnsnotwanted = array(3,4,20);  //indexes of columns don't want display     while (($line = fgetcsv($f)) !== false) {             echo "<tr>";             $numcolumn=0;             foreach ($line $cell) {                 if(!in_array($numcolumn,$idscolumnsnotwanted)                     echo "<td>" . htmlspecialchars($cell) . "</td>";                 $numcolumn++;             }             echo "</tr>\n";     }     fclose($f);     echo "\n</table>";
