Good question.
It depends, at least in part, on HOW you're using PHP to read the URL.
Here's an example snippet, that uses PHP's built-in "DOMDocument" class:
http://www.softarea51.com/tutorials/..._php.html#code
Code:
<?php
$doc = new DOMDocument();
$doc->load('http://www.softarea51.com/rss/windows/Web_Development/XML_CSS_Utilities.xml');
$arrFeeds = array();
foreach ($doc->getElementsByTagName('item') as $node) {
$itemRSS = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue
);
array_push($arrFeeds, $itemRSS);
}
?>
I believe in this example, the server (
www.software51.com) wouldn't see ANY user agent ... because I don't believe DOMDocument->load() writes one in its httpd header.
You can easily verify this by using the above code to access a sample xml document on your own web server, and see what the web server reports (e.g. look at your access_log).
