Detailed description and usage:
See this example:
$rss=new RSS_parser();
$rss->rss_parse("http://www.phpclasses.org/browse.html/latest/latest.xml");
$ch=$rss->get_channel_data();
$ch_im=$rss->get_channel_image_data();
$ch_ti=$rss->get_channel_textinput_data();
$items=$rss->get_items_data();
The rssdump example shows how to use the information returned by the methods, the structures returned by the get methods are:
- $ch: channel data: an asoc array with channel information (if present)
- $ch_im: channel image data: an asoc array with channel image information (if present)
- $ch_ti: channel textinput data: an asoc array with channel textinput information (if present)
