比较两个stdClass对象

Question

我目前正在研究Wordpress主题中的修改搜索，该主题查询自定义分类标准location并将其术语显示为搜索结果。我无法找到一个内置在WordPress的功能，以处理这个问题，所以我用一个$wpdb query

$keywords = $_GET['s']; 
$results = $wpdb->get_results("SELECT * FROM $wpdb->terms WHERE name LIKE '%%$keywords%%'"); 

<ul> 
<?php foreach ($results as $result) :?> 
    <li><?php echo $result->name;?></li> 
<?php endforeach;?> 
</ul> 

的问题与此是表wp_terms不仅存储自定义分类方面，但其他默认条款以及。因此，为了显示搜索结果只是为自定义分类，而不是其他默认的条款，我想用get_terms获得基于关闭的get_terms结果与in_array都属于自定义分类从表wp_termslocation和显示方面的条款的

$keywords = $_GET['s']; 
$results = $wpdb->get_results("SELECT * FROM $wpdb->terms WHERE name LIKE '%%$keywords%%'"); 

$terms = get_terms("location"); 

<ul> 
<?php foreach ($results as $result) :?> 
    if(in_array($result->name, $terms)) :?> 
    <li><?php echo $result->name;?></li> 
    <?php endif;?> 
<?php endforeach;?> 
</ul> 

然而，$results和$terms都是stdClass的对象，所以in_array不起作用。

是否有一个函数，方法或MySQL查询，这将允许我显示对象$results的结果基于对象的内容$terms？

在此先感谢。

编辑： 内容的$terms

Array ( 
    [0] => stdClass Object ([term_id] => 32 [name] => US [slug] => us [term_group] => 0 [term_taxonomy_id] => 32 [taxonomy] => signs [description] => [parent] => 25 [count] => 1) 
    [1] => stdClass Object ([term_id] => 22 [name] => EU [slug] => eu [term_group] => 0 [term_taxonomy_id] => 22 [taxonomy] => signs [description] => [parent] => 0 [count] => 3) 
    [2] => stdClass Object ([term_id] => 26 [name] => AU [slug] => au [term_group] => 0 [term_taxonomy_id] => 26 [taxonomy] => signs [description] => [parent] => 22 [count] => 1) 
    [3] => stdClass Object ([term_id] => 27 [name] => IE [slug] => ie [term_group] => 0 [term_taxonomy_id] => 27 [taxonomy] => signs [description] => [parent] => 22 [count] => 2) 
    [4] => stdClass Object ([term_id] => 23 [name] => PK [slug] => pk [term_group] => 0 [term_taxonomy_id] => 23 [taxonomy] => signs [description] => [parent] => 0 [count] => 2) 
)

你可以将它们转换成阵列，

(array) $variable; 

或者，如果您stdClass已经包含嵌套stdClasses，你可以做到以下几点：

function obj_to_array_recursive(stdClass $obj) { 
    foreach ($obj as &$element) { 
     if ($element instanceof stdClass) { 
      obj_to_array_recursive($element); 
      $element = (array)$element; 
     } 
    } 
    $obj = (array)$obj; 
    return $obj; 
}
