Read and RSS feed

With this function you can read any rss feed you want!

<?php

function readRSSFile($filename) {
        $data = implode('', file($filename));
        $parser = xml_parser_create();
        xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
        xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
        xml_parse_into_struct($parser, $data, $values, $tags);
        xml_parser_free($parser);

        foreach ($tags as $key => $val) {
                if ($key == 'item') { // select the 'items'
                        $itemRanges = $val;
                        for($i=0; $i<count($itemRanges); $i+=2) {
                                $offset = $itemRanges[$i] + 1;
                                $len = $itemRanges[$i + 1] - $offset;
                                $result[] = combineItem(array_slice($values, $offset, $len));
                        }
                }
        }
        return $result;
}
function combineItem($itemValues) {
        for ($i=0; $i<count($itemValues); $i++) {
                if(isset($itemValues[$i]['value'])) {
                        $item[$itemValues[$i]['tag']] = $itemValues[$i]['value'];
                }
        }
        return $item;
} 



//To Read an RSS file
$latest = readRSSFile("RssFeedHere.rss");
for($i=0; $i<count($latest); $i++) {
        print'<p>'.$latest[$i]['description'].'</p>';
} 

?>

Usage

Copy the two above functions to your includes file.
And use the second snippet to ready any RSS feed you want!

You can use the function in an other var.
In the code above i used $latest = readRSSFile("");
You can use another like: $otherVar = readRSSFile("");
And than in the for loop use $otherVar.
