Parsing table and removing excess data - php

Question

Im using the simpel dom parser to retrieve som data. But when i changed the table layout the parser stopped working. Im getting error PHP Fatal error: Call to a member function find() on null.
require('simple_html_dom.php');
$html = file_get_html($url);
$table = $html->find('table');
$rowData = array();
foreach($table->find('tr') as $row) {
// initialize array to store the cell data from each row
$stocks = array();
foreach($row->find('td') as $cell) {
// push the cell's text to the array
$stocks[] = $cell->plaintext;
}
$rowData[] = $stocks;
}
echo '<table>';
foreach ($rowData as $row => $tr) {
echo '<tr>';
foreach ($tr as $td)
echo '<td>' . $td .'</td>';
echo '</tr>';
}
echo '</table>';
Have a look at this pastebin (sorry for big table layout). It is from this table i want to extract the following th
+--------+--------+------+----+------+-------+--------+--------+---------+
| Aktie | Senast | +/- | % | Köp | Sälj | Högst | Lägst | Omsatt |
+--------+--------+------+----+------+-------+--------+--------+---------+
This snipp works, but it doesn't arrange the data in a table:
require('simple_html_dom.php');
$html = file_get_html($url);
// remove all image
foreach($html->find('img') as $e)
$e->outertext = '';
// Remove a attribute, set it's value as null!
foreach($html->find('a') as $e)
$e->href = null;
// Find all <td> in <table> which class=hello
foreach($html->find('table tr') as $es)
echo $es->innertext . '<br>';
My question:
How can i fetch the above mentioned th? and insert the corresponding data from td column?
Expected result is:
+-------------+--------+-------+-------+-------+-------+--------+--------+---------+
| Aktie | Senast | +/- | % | Köp | Sälj | Högst | Lägst | Omsatt |
+-------------+--------+-------+-------+-------+-------+--------+--------+---------+
| AAK AB | 549,90 | ..etc | ..etc | ..etc | ..etc | ..etc | ..etc | ..etc |
| ABB LTD | 149.80 | ..etc | ..etc | ..etc | ..etc | ..etc | ..etc | ..etc |
| and so on.. | | | | | | | | |
+-------------+--------+-------+-------+-------+-------+--------+--------+---------+

Answer 1

Do you have more than one table? If so, explicitly identify the table id
Get header: $e = $table->find('thead'); and do something to it get the table data, as you already did, and I would imagine that the indexes could implicitly create the relation between header and data.
