PHP 根据键显示数组中对象的值

Question

我有以下数组，其中包含对象和数组。我如何根据它们的键仅获取特定值（对于每个对象）？我已经测试过并且数组正在显示（见下文）但我无法根据需要隔离“名称”值。

我尝试了以下代码来获取名称值：

case 'field_prgm_housing' :
$node = 'field_color';
$tids =  field_get_items('node', $node, $key, $node->language);
$terms = taxonomy_term_load_multiple(array(), array('tid' => $tids));
$nameonly = $terms->[0]->name[0];
return = $nameonly;
break;      
Colors (Array, 2 elements)
    12 (Object) stdClass
      tid (String, 2 characters ) 12
      vid (String, 1 characters ) 3
      name (String, 9 characters ) Blue
      description (String, 0 characters )
      format (String, 13 characters ) filtered_html
      weight (String, 1 characters ) 0
      vocabulary_machine_name (String, 15 characters ) colors
      rdf_mapping (Array, 5 elements)
      path (Array, 1 element)
    13 (Object) stdClass
      tid (String, 2 characters ) 13
      vid (String, 1 characters ) 3
      name (String, 8 characters ) Green
      description (String, 0 characters )
      format (String, 13 characters ) filtered_html
      weight (String, 1 characters ) 0
      vocabulary_machine_name (String, 15 characters ) colors
      rdf_mapping (Array, 5 elements)
      path (Array, 1 element)

Answer 1

Try this


    $node = 'field_color';
    $tids =  field_get_items('node', $node, $key, $node->language);
    $terms = taxonomy_term_load_multiple(array(), array('tid' => $tids));

    //loop all the values and get the require value
   $name = array();
    foreach($terms as $term){
          $name[] = $term->name;
    }
    return $name;

Answer 2

$terms->[0] 是什么意思？

$terms 是一个数组，因此您必须通过指定要获取的索引来访问它，例如：$terms[12], $terms[13]...

该数组的元素是对象，因此当您获得一个时，您必须使用“->”运算符来获取它的字段（或方法）。

所以它必须是这样的：

$nameonly = $terms[12]->name;
$nameonly = $terms[13]->name;

或者您可以按照@kranthi 的建议遍历所有数组项。
