Question

I want to get news_keywords from this meta:

 <meta name="news_keywords" content="bla, bla, bla tag">
 <meta property="og:title" content="title example">

i try with simple code and doesn't work

 $tags = get_meta_tags($link);
 echo $tags['news_keywords'];

Answer 1

That's a minor mistake. Change it to:

echo $tags['news_keywords'];

Outputs:

bla, bla, bla tag
