PHP & Wordpress: print array content

Question

I'm to dumb right now …

print_r($terms);

does this …

Array
(
    [7] => stdClass Object
        (
            [term_id] => 7
            [name] => Testwhatever
            [slug] => testwhatever
            [term_group] => 0
            [term_taxonomy_id] => 7
            [taxonomy] => event_type
            [description] => 
            [parent] => 0
            [count] => 2
            [object_id] => 8
        )

)

How can I print the slug? I thought print print($terms->slug) should do the job, but it says: "Trying to get property of non-object"

update:

function get_event_term($post) {
    $terms = get_the_terms( (int) $post->ID, 'event_type' );
    if ( !empty( $terms ) ) {
        print_r($terms);
        return $terms[7]->slug;
    }
}

Solution 1

Its an array of objects (even if it contains only a single entry at index "7"), not a single object

echo $terms[7]->slug;

With multiple "things

foreach ($terms as $term) echo $term->slug;

Solution 2

try

print_r($terms[7]->slug);

you object stdclass is in array[7] offset.

Solution 3

Or, to complicate things a little bit:

array_walk($terms, function($val,$key) use(&$terms){ 
    var_dump($val->slug);
});

Thank you, I updated my question. The problem is that this "7" is a dynamic number specifically for each post in wordpress. I have no idea what number it is. It doesn't seem to be the post->ID

@matt Array $terms always has one element, or it could have more?

[matt]

it could have more I guess. Normally it's set to one, but it is possible to add multiple terms to a post.
