我是否知道如何使用PHP检索以下示例中每个数组中给定的Name和middle name值？谢谢。

object(stdClass)#13 (1) 
{ ["contact"]=> array(157) { 
    [0]=> object(stdClass)#14 (6) {

Answer 1

要访问您将使用的第一个（未经测试）：

$myObject->contact[0]->fields[1]['value']['middleName'];

Answer 2

您需要阅读var dump types 以确定如何访问数据结构。如果它显示object（例如，在您的转储中首先列出object(stdClass)#13），那么您将使用->运算符来访问列出的元素（例如$object->contact）。如果它显示array，则可以使用索引表示法[0]，或者，如果有多个元素，则使用循环结构进行迭代：

foreach ($object->contact as $contact) {
    foreach ($contact->fields as $field) {
        if ($field->type == 'name') {
            echo $field->value->givenName, ' ', echo $field->value->middleName;
        }
    }
}

Answer 3

您应该使用两个嵌套的foreach循环和property_exists()，如下所示：

foreach( $obj->contact as $contact){
  foreach( $contact->fields as $field){
    if( property_exists( $field, 'givenName') &&
       property_exists( $field, 'middleName')){

       // Or use if( $field->type == 'name') as webbiedave suggested

       // Here goes your desired values
       // Do whatever you want with them
       $field->givenName;
       $field->middleName;

       // If you want only one set of names per each contact, add break here
    }
  }

  // Here goes handling for contacts wit no desired information
}

用PHP读取var_dump数据
