I recently purchased the WS-1400-IP weather station from Ambient Weather that links up to Weather Underground. I am attempting to do a DOM query on the HTML of the IP link device. Here is my code:
(I know its very crude code, it's just a preliminary thing).
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$filename = "http://10.175.3.28/bscsetting.htm";
$html = file_get_contents($filename);
echo "<input type=text value='{$html}'></input>";
$dom = new DOMDocument();
@$dom->loadHTML($html);
$x = new DOMXPath($dom);
$data = array();
foreach($x->query("//input") as $node)
{
$data[][$node->getAttribute("name")] = $node->getAttribute("value");
}
echo json_encode($data, JSON_PRETTY_PRINT);
And this is what I am seeing when I echo the HTML I am getting from the device:
<input type=text value='ction: Keep-Alive
Content-type: text/html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=big5">
<meta http-equiv="refresh" content="0;URL=./bscsetting.htm">
<title></title>
<body leftmargin="80" topmargin="80" marginwidth="80" marginheight="0" bgcolor="#333">
<font size="+3"><strong><p align="center"></p></strong></font>
</body>
</html>
'></input>[
]
And here is what I should be seeing (as this is what I see when I use a regular browser):

How do I get past the meta refresh? Any ideas?
EDIT: After trying curl, it works as expected.. Why would it make a difference?
