<table class="infobox biota" style="text-align: left; width: 200px; font-size: 100%">

Here is my attempt to parse and obtain the kingdom,phylum,subphylum,class,order and family of a rabbit with the table structure. However I get a the following Array ( [Kingdom:] => [Phylum:] => [Subphylum:] => [Class:] => [Order:] => [Family:] => [
Pentalagus
Bunolagus
Nesolagus
Romerolagus
] => )
it doesnt fill in the array with the data for the rabbit. also it give me a parse error in the line shown below, what can be wrong?
<?php
//require"mydb.php";
header('Content-type: text/html; charset=utf-8'); // this just makes sure encoding is right
include('simple_html_dom.php'); // the parser library
$html = file_get_html('http://en.wikipedia.org/wiki/Rabbit');
$table = $html->find('table.infobox');
$data = array();
foreach($table[0]->find('tr') as $row)
{
$td = $row->find('> td');
if (count($td) == 2)
{
$name = $td[0]->innertext;
$text = $td[1]->find('a')[0]->innertext; //PARSE ERROR IS GIVEN HERE, after the find('a')[0], taking off the array takes away the error but just me no results
$data[$name] = $text;
}
}
print_r($data);
?>

Answer 1

$text = $td[1]->find('a')[0]->innertext;
In this line you are dereferencing a function. This is only available in PHP 5.4 or later. Try this instead:
$td = $td[1]->find('a');
$text = $td[0]->innertext;
