Simple HTML Dom - parse only few columns from original table - php

Question

I want to copy some table to my website, but only with few specific columns
Here is my code
<?php
require('simple_html_dom.php');
$html = file_get_html('http://pomorskifutbol.pl/liga.php?id=970');
$table = $html->find('table', 0);
$rowData = array();
foreach($table->find('tr') as $row) {
// initialize array to store the cell data from each row
$flight = array();
foreach($row->find('td') as $cell) {
// push the cell's text to the array
$flight[] = $cell->plaintext;
}
$rowData[] = $flight;
}
echo '<table>';
foreach ($rowData as $row => $tr) {
echo '<tr>';
foreach ($tr as $td)
echo '<td>' . $td .'</td>';
echo '</tr>';
}
echo '</table>';
?>
whole table
And this prints whole table, I want to get only few columns, for example only "M.", "Drużyna", "M", "PKT"
How extract only this columns from this table?

Answer 1

You can change the entry:
foreach($row->find('td') as $cell) {
to
foreach($row->find('td') as $columnNumber => $cell) {
and make an if before the filling of the $flights array, e.g
//somewhere in code
$columnNumbers = [ 0, 2, 3,4, 7];
// int the foreach loop
if ( in_array( $columnNumber, $columnNumbers ) ) {
$flight[] = $cell->plaintext;
}
