Create an Array from data - php

Question

I am trying to create an array from this data, but I don´t get it. I tried with the array_merge function, but the array doesn't construct correctly. This is my code, I want to create an array with the different fields of the table.
<?php
require('extractorhtml/simple_html_dom.php');
$dom = new DOMDocument();
//load the html
$html = $dom->loadHTMLFile("http:");
//discard white space
$dom->preserveWhiteSpace = false;
//the table by its tag name
$tables = $dom->getElementsByTagName('table');
//get all rows from the table
$rows = $tables->item(0)->getElementsByTagName('tr');
echo '<input type="text" id="search" placeholder="find" />';
echo '<table id="example" class="table table-bordered table-striped display">';
echo '<thead>';
echo '<tr>';
echo '<th>Date</th>';
echo '<th>Hour</th>';
echo '<th>Competition</th>';
echo '<th>Event</th>';
echo '<th>Chanel</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
// loop over the table rows
foreach ($rows as $row)
{
// get each column by tag name
$cols = $row->getElementsByTagName('td');
// echo the values
echo '<tr>';
echo '<td>'.$cols->item(0)->nodeValue.'</td>';
echo '<td>'.$cols->item(1)->nodeValue.'</td>';
echo '<td>'.$cols->item(3)->nodeValue.'</td>';
echo '<td class="text-primary">'.$cols->item(4)->nodeValue.'</td>';
echo '<td>'.$cols->item(5)->nodeValue.'</td>';
echo '</tr>';
}
echo '</tbody>';
echo '</table>';
?>

Answer 1

You don't need to merge arrays, you just need to push onto a new array to create a 2-dimensional array.
$new_array = array();
foreach ($rows as $row)
{
// get each column by tag name
$cols = $row->getElementsByTagName('td');
// echo the values
echo '<tr>';
echo '<td>'.$cols->item(0)->nodeValue.'</td>';
echo '<td>'.$cols->item(1)->nodeValue.'</td>';
echo '<td>'.$cols->item(3)->nodeValue.'</td>';
echo '<td class="text-primary">'.$cols->item(4)->nodeValue.'</td>';
echo '<td>'.$cols->item(5)->nodeValue.'</td>';
echo '</tr>';
$new_array[] = array(
'date' => $cols->item(0)->nodeValue,
'hour' => $cols->item(1)->nodeValue,
'competition' => $cols->item(3)->nodeValue,
'channel' => $cols->item(5)->nodeValue
);
}

Based on your <th> values, you know which columns contain which values, so it looks like you'd just need to modify the code inside your foreach loop to append the values to an array rather than generating new HTML with them.
foreach ($rows as $row)
{
// get each column by tag name
$cols = $row->getElementsByTagName('td');
$array['date'] = $cols->item(0)->nodeValue;
$array['hour'] = $cols->item(1)->nodeValue;
$array['competition'] = $cols->item(3)->nodeValue;
$array['event'] = $cols->item(4)->nodeValue;
$array['chanel'] = $cols->item(5)->nodeValue;
$result[] = $array;
}
After this loop, $result will be an array of arrays containing the values from the <td>s, where each inner array represents one <tr>.
