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

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);

More info on this on the [Wordpress Docs][1]

By using this you should get data returned like this...

Array
(
[0] => stdClass Object
(
[term_id] => 4
[name] => tag2
[slug] => tag2
[term_group] => 0
[term_taxonomy_id] => 4
[taxonomy] => post_tag
[description] =>
[parent] => 0
[count] => 7
)

[1] => stdClass Object
(
[term_id] => 7
[name] => tag5
[slug] => tag5
[term_group] => 0
[term_taxonomy_id] => 7
[taxonomy] => post_tag
[description] =>
[parent] => 0
[count] => 6
)

)

Now what I want is the slug for the first item which should be as follows

$tag[0]['slug']

However by doing so I recieve this php error:

> Cannot use object of type stdClass as
> array

Can someone tell me what I'm doing wrong here? and whats the best way to get the slug data

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

$tag[0]->slug

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
