Echo specific line from each array

Question

I have the following dynamically generated array. The array values can change each time, but the positions remain the same (i.e. name will always be the 2nd item for each array).

How would I echo the same specific line from each array? For example, say I wanted all the names echoed together?

Array
(
    [0] => WP_Term Object
        (
            [term_id] => 437
            [name] => 128 GB
            [slug] => 128-gb
            [term_group] => 0
            [term_taxonomy_id] => 437
            [taxonomy] => pa_phone-capacity
            [description] => 
            [parent] => 0
            [count] => 88
            [filter] => raw
        )

    [1] => WP_Term Object
        (
            [term_id] => 19
            [name] => AT&T
            [slug] => att
            [term_group] => 0
            [term_taxonomy_id] => 19
            [taxonomy] => pa_phone-carrier
            [description] => 
            [parent] => 0
            [count] => 288
            [filter] => raw
        )

    [2] => WP_Term Object
        (
            [term_id] => 280
            [name] => Flawless
            [slug] => flawless
            [term_group] => 0
            [term_taxonomy_id] => 280
            [taxonomy] => pa_phone-condition
            [description] => Works perfectly.

            [parent] => 0
            [count] => 338
            [filter] => raw
        )

    [3] => WP_Term Object
        (
            [term_id] => 442
            [name] => iPhone
            [slug] => iphone
            [term_group] => 0
            [term_taxonomy_id] => 442
            [taxonomy] => pa_device
            [description] => 
            [parent] => 0
            [count] => 496
            [filter] => raw
        )

    [4] => WP_Term Object
        (
            [term_id] => 284
            [name] => iPhone 6 Plus
            [slug] => iphone-6-plus
            [term_group] => 0
            [term_taxonomy_id] => 284
            [taxonomy] => pa_phone-model
            [description] => 
            [parent] => 0
            [count] => 72
            [filter] => raw
        )

    [5] => WP_Term Object
        (
            [term_id] => 443
            [name] => Smartphone
            [slug] => smartphone
            [term_group] => 0
            [term_taxonomy_id] => 443
            [taxonomy] => pa_device
            [description] => 
            [parent] => 0
            [count] => 1352
            [filter] => raw
        )

I need a solution that will remain dynamic. Sometimes there might be 8 term objects, sometimes there might only be 5 like in the above array. term_id will always be the first, name will always be the second, so on and so forth.

This has been eluding me for at least an hour now and its frustrating me so much :(

Answer 1

echo implode(", ", array_map(function(WP_Term $term){
    return $term->name;
}, $array));

Answer 2

You need iterate the array to print the name or any other property of that object.

$terms = get_terms();
$length = count($terms);
$counter = 1; 
foreach($terms as $term) {
    echo isset($term->name) ? $term->name : '';
    echo ($counter != $length) ? PHP_EOL : ''; //Any separator 
    $counter++;
}
