<?
$meta = get_meta_tags('https://codepad.co/');
$keywords = $meta['keywords'];
// Split keywords
$keywords = explode(',', $keywords );
// Trim them
$keywords = array_map( 'trim', $keywords );
// Remove empty values
$keywords = array_filter( $keywords );
print_r( $keywords );
A great code snippet to extract easily meta keywords from any webpage.
