How to echo WP SEO Yoast synonyms in PHP

Question

I need to print a page including WPSEO information, for translation. I am trying to output WPSEO information in PHP, and I have managed for title, description, focus keywords, but it does not work for synonyms . There seems to be no Meta for synonym, so how to get it?

Answer 1

 the meta_key in wp_postmeta table is _yoast_wpseo_keyword synonyms, 

Title: "<?php echo WPSEO_Meta::get_value("title"); ?>"<br />
Description: "<?php echo WPSEO_Meta::get_value("metadesc"); ?>"<br />
Focus Keyword: "<?php echo WPSEO_Meta::get_value("focuskw"); ?>"<br />
Synonyms: "<?php echo substr(get_post_meta( $post->ID, '_yoast_wpseo_keywordsynonyms', true ), 2, -5); ?>"<br />
</div>```
