Getting information from Google Calendar using php's domdocument - php

Question

Below is the code. It seems to not be opening the google calendar at all. I believe it has something to do with the url I am using and possbily the special character. I get the following:
Warning: DOMDocument::loadHTMLFile() [domdocument.loadhtmlfile]: I/O warning : failed to load external entity "https://www.google.com/calendar/feeds/tjd#dreilinginc.com/public/basic" on line 4
<?
$dom = new DOMDocument();
$feed = "https://www.google.com/calendar/feeds/tjd#dreilinginc.com/public/basic";
$html = $dom->loadHTMLFile($feed);
$dom->preserveWhiteSpace = true;
$entries = $dom->getElementsByTagName("entry");
foreach ( $entries as $entry )
{
$status = $entry->getElementsByTagName( "eventStatus" );
$eventStatus = $status->item(0)->getAttributeNode("value")->value;
if ($eventStatus == $confirmed)
{
$titles = $entry->getElementsByTagName( "title" );
$title = $titles->item(0)->nodeValue;
$times = $entry->getElementsByTagName( "when" );
$startTime = $times->item(0)->getAttributeNode("startTime")->value;
$when = date( "l jS \o\f F Y - h:i A", strtotime( $startTime ) );
$places = $entry->getElementsByTagName( "where" );
$where = $places->item(0)->getAttributeNode("valueString")->value;
print $title . "\n";
print $when . " AST\n";
print $where . "\n";
print "\n";
}
}
?>

As far as I know, DOMDocument::loadHTMLFile() is capable of negotiating SSL, but if it is failing you might try file_get_contents() to read the file first into a string.
$dom = new DOMDocument();
$feed = "https://www.google.com/calendar/feeds/tjd#dreilinginc.com/public/basic";
$feed_string = file_get_contents($feed);
$html = $dom->loadHTMLFile($feed_string);
This is fully speculative though. Treat it as such.
EDIT Make sure that allow_url_fopen is enabled in your php.ini.
