Hacking a filter for Twitter

The following php script fetches a Twitter RSS feed and filters out all the irrelevant comments you made.

<?
// replace url with your twitter rss feed
$lines = file( "http://twitter.com/statuses/user_timeline/1234567890.rss" );

$skip = false;
$c = count( $lines );
for ( $i = 0; $i < $c; $i++ ) {
    $line = $lines[$i];

    $p = strpos( $line, "<item>" );
    if ( $p !== false ) {
        // Replace YourName with your twitter account name
        $p2 = strpos( $lines[$i+1], "YourName: @" );
        if ( $p2 !== false ) {
            $skip = true;
        }
    }

    if ( $skip ) {
        if ( strpos( $line, "</item>" ) !== false ) {
            $skip = false;
        }
    } else {
        echo $line;
    }
}
?>
