'Cannot use object of type stdClass as array' using Wordpress

Question

I am trying to retrieve the slug for a tag inside a wordpress post, now its possible to get all tag info using

$tag = wp_get_post_tags($post->ID);


        

Answer 1

Another option should be to explicitly cast $tag[0] into an array:

$t = (array)$tag[0];
$t["slug"] = ...

Can't get it to work though

Answer 2

Note that the array contains objects (instances of stdClass), not other arrays. So the syntax is:

$tag[0]->slug
