检查一个关联数组是否有一个特定的值

Question

我有一个关联数组，其中包含来自WordPress Post的标记列表。这是一个WordPress函数的输出wp_get_post_tags

array(3) { [0]=> object(WP_Term)#300 (10) { ["term_id"]=> int(22) ["name"]=> string(10) "Case Study" ["slug"]=> string(10) "case-study" ["term_group"]=> int(0) ["term_taxonomy_id"]=> int(22) ["taxonomy"]=> string(8) "post_tag" ["description"]=> string(0) "" ["parent"]=> int(0) ["count"]=> int(6) ["filter"]=> string(3) "raw" } [1]=> object(WP_Term)#295 (10) { ["term_id"]=> int(9) ["name"]=> string(9) "Microsoft" ["slug"]=> string(9) "microsoft" ["term_group"]=> int(0) ["term_taxonomy_id"]=> int(9) ["taxonomy"]=> string(8) "post_tag" ["description"]=> string(0) "" ["parent"]=> int(0) ["count"]=> int(11) ["filter"]=> string(3) "raw" } [2]=> object(WP_Term)#367 (10) { ["term_id"]=> int(27) ["name"]=> string(10) "SharePoint" ["slug"]=> string(10) "sharepoint" ["term_group"]=> int(0) ["term_taxonomy_id"]=> int(27) ["taxonomy"]=> string(8) "post_tag" ["description"]=> string(0) "" ["parent"]=> int(0) ["count"]=> int(10) ["filter"]=> string(3) "raw" } } 

，我要检查它是否包含标签名称“的SharePoint”。我经历了各种资源，但找不到办法。这是阵列

Array 
(
    [0] => stdClass Object 
     (
      [term_id] => 4 
      [name] => tag2 
      [slug] => tag2 
      [term_group] => 0 
      [term_taxonomy_id] => 4 
      [taxonomy] => post_tag 
      [description] => 
      [parent] => 0 
      [count] => 7 
     ) 

    [1] => stdClass Object 
     (
      [term_id] => 7 
      [name] => tag5 
      [slug] => tag5 
      [term_group] => 0 
      [term_taxonomy_id] => 7 
      [taxonomy] => post_tag 
      [description] => 
      [parent] => 0 
      [count] => 6 
     ) 

    [2] => stdClass Object 
     (
      [term_id] => 16 
      [name] => tag6 
      [slug] => tag6 
      [term_group] => 0 
      [term_taxonomy_id] => 16 
      [taxonomy] => post_tag 
      [description] => 
      [parent] => 0 
      [count] => 2 
     ) 

) 

做这个我试过的结构，但它没有工作

//$a is the Array 
foreach ($a as $key=>$value) { 
if ($value=='SharePoint'){ 
echo "True" 
} 

请帮助。

你接近，但不要忘记$值是一个对象，所以你的代码应该调整这种方式：

foreach ($a as $key=>$value) { 
if ($value->name=='SharePoint'){ 
echo "True"; 
}
