Question

我有以下动态生成的数组。数组值每次都可以更改，但位置保持不变（即名称将始终是每个数组的第2项）。

我如何回应每个阵列中相同的特定线？例如，假设我想让所有名字一起回响？

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.

No noticeable flaws, still in its package or looks like new.

            [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
        )

我需要一个保持动态的解决方案。有时候可能会有8个术语对象，有时在上面的数组中可能只有5个。 term_id将始终是第一个，名称将始终是第二个，依此类推。

这已经让我至少躲过了一个小时，这让我非常沮丧:(

Answer 1

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

Answer 2

您需要迭代数组以打印该对象的名称或任何其他属性。

$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++;
}

Answer 3

例如，您的数组名称是$ items。

Foreach($items as item){
       Echo $item->name;
}

Answer 4

使用此

$cats = $cats = get_the_terms($post->ID, 'themes_categories');
foreach ($cats as $key => $object) {
echo $object->name;
}

每个阵列的Echo特定线
