使用PHP Simple HTML DOM获取表值

Question

I'm writing this PHP to read the data from the following website, and the write it into database.

Here's the code:

<?php
require('simple_html_dom.php');
$html = file_get_html('http://backpack.tf/pricelist/spreadsheet');
$data = $html->find('.table tr td[1]');  
foreach($data as $result)
{
echo $result->plaintext . '<br />';
}
?>

I intended to get all the data in the tds and even the attribute inside the trs.
So, I tried by getting them in plain text first. By far the code returns:

Fatal error: Call to a member function find() on a non-object

How can I solve and improve the code?

Answer 1

The following code is working for your example. It could be the memory limit for your executing script that's causing trouble.

ini_set('memory_limit','160M');
require('simple_html_dom.php');
$url = 'http://backpack.tf/pricelist/spreadsheet';

$html = new simple_html_dom();
$html->load_file($url);

$data = $html->find('.table tr td[1]');  
foreach($data as $result)
{
    echo $result->plaintext . '<br />';
}
