PHP array splice not working

Question

I'm trying to build a shortcode in wp that displays data from 2 RSS feeds.

The problem is that I can't limit the number of items in array. I tried these solutions and none worked.

function rss_posts_func( $atts ){
    $feed = fetch_feed(array('rss-feed-1', 'rss-feed-2'));
    $feed = array();
    $feed = array_splice($feed, 0, 3);
    // Loop the results
     $content = '<ul class="rss-aggregator">';
    foreach($feed->get_items() as $item) {
        $content .= '<li class="feed-item">';
        $content .= '<a href='.$item->get_permalink().'>';
        $content .= $item->get_title();
        $content .= '</a></li>';
    }
    $content .= '</ul>';
    return $content;
}

Answer 1

Fixed with:

function rss_posts_func( $atts ){
    $i = 1;
    $feed = fetch_feed(array('rss-feed-1', 'rss-feed-2'));
     $content = '<ul class="rss-aggregator">';
    foreach($feed->get_items() as $item) {
        $content .= '<li class="feed-item">';
        $content .= '<a href='.$item->get_permalink().'>';
        $content .= $item->get_title();
        $content .= '</a></li>';
        if($i++ == 8) break;
    }
    $content .= '</ul>';
    return $content;
}
