Description:

Hi,

First of all, thanks for your package, we are using it @ Jaws Project for supporting pingback.

The reason of this 'bug report' is to let you know a little bug I found. Currently you validate an URI by calling fopen which is *OK*, however fopen has some limitations with some URLs (like those that use query strings or path info: index.php/foo/bar).

And example of this happens when the discover/source/target URIs are very similar to http://www.example.com/index.php/foo/bar (using PATH_INFO). With the current release it will return false which is not correct cause maybe the sourceURI/targetURI uses PATH_INFO (like WP/Jaws/others).

So, the most *reasonable* way to fix this is to do the same that RPC (and some parts of Pingback) does: use fsockopen/HTTP_Request which does:

1. Open a socket (fsockopen)
2. Get headers
3. If responseCode == 200 then the URI is valid.

I'm sending a patch for this (already tested with some WP/Jaws posts).

Thanks for the package!

Test script:
---------------
function isURIExist($uri)
{
$params = array(
'timeout' => 3,
'allowRedirects' => true,
'maxRedirects' => 2,
);

$req = new HTTP_Request($uri, $params);

$req->sendRequest();
if (PEAR::isError($req)) {
return false;
}

if ($req->getResponseCode() == 200) {
return true;
}
return false;
}
