Display your recent delicious bookmarks with PHP

Reading time: About 1 minute

This tutorial uses PHP5 to download and cache your recent bookmarks in RSS format from the Delicious API, then displays them in a HTML unordered list.

See this in action on my “Recommended” page under “Recently bookmarked links.”

	foreach($xml as $item)
	{
		$html .= '<li><a href="' . $item['href'] . '">' . $item['description'] . '</a> ' . $item['extended'] . '</li>';
	}
	$html .= '<li><a href="http://delicious.com/briancray">More of Brian Cray\'s delicious bookmarks&hellip;</a></li>';
	$html .= '</ul>';
	echo $html;
}
 
// display them
get_delicious();

This tutorial uses SimpleXML. SimpleXML has been included in PHP5 to make reading XML files into PHP variables much, well, simpler.

    Awesome, thanks.
    One possible correction that you may have overlooked:

    line 4 should be:
    if(filemtime($cache) < (time() – 300))

    Brian,
    Right on, I would suppress the mkdir warning using @mkdir (this would help users who have no experience customizing their php.ini file).

    Just a suggestion – and thanks again for the tutorial.

    This was awesome, thanks. Just two questions…

    It works perfectly on my hosting, but not my localhost using latest version of MAMP… do you have any suggestions for how I could either blind guess the problem right on my local or extra lines that’ll echo back what the problem could be.

    Also, how secure is this? One of my friends mentioned to add some extra lines to encript the data and store the password somewhere else. Any other thoughts?

    Thanks!

    To use yahoo account you should simply modify v1 to v2 in the url used. More information on this in delicious api site
