Answer 1

$urls = array();

foreach ( $html->find('a') as $e )
{
    // If it's a twitter link
    if ( strpos($e->href, '://twitter.com/') !== false )
    {
        // and we don't have it in the array yet
        if ( ! in_array($e->href, $urls) )
        {
            // add it to our array
            $urls[] = $e->href;
        }
    }
}

echo implode('<br>', $urls);

Here are some references from the PHP docs:

• strpos
• in_array
• implode
