未定义的偏移量：1 in AND尝试获取非对象的属性

Question

我成功导入了与yahoo Oauth API的电子邮件联系。我可以看到，当我回复它时，我的所有联系电子邮件都列在页面中。但是，虽然打印电子邮件成功，但有一条错误消息：

Trying to get property of non-object in globalses.php on line 295 AND Undefined offset: 1 in globalses.php on line 295

这是显示错误的代码：

  if (! empty($response)) {
    list($info, $header, $body) = $response;
    if ($body) {
      //logit("callcontact:INFO:response:");
      //print(json_pretty_print($body));
      $yahoo_array = json_decode($body);

     echo "<pre/>";
     //print_r($yahoo_array);
     foreach($yahoo_array as $key=>$values){


         foreach($values->contact as $keys=>$values_sub){
            // echo '<pre/>';
            // print_r($values_sub);
            // echo $values_sub->fields[1]->value->givenName;
             $email = $values_sub->fields[1]->value; //This is line 295

            if(trim($email)!="")
            $newList   .= $email.",";

         }
     }

    }
    $retarr = $newList."";
  }

  return $retarr;

[更新] $values->contact

的打印结果

Answer 1

您正在按以下字段访问该电子邮件：

 $email = $values_sub->fields[1]->value; //This is line 295

当您看到数组的第一个元素时，没有任何带有键1的字段，因为它只是数组中的值。 $fields[0].

通过查看您的代码和实际数组，我想出了以下内容，这可能不是完整的解决方案，但希望指导结果。

所以这必须是这样的：

foreach($values->contact as $keys=>$values_sub){
            $fields = $values_sub->fields;
            foreach($fields as $field){
                if(property_exists($field,'value') && !is_array($field->value)){
                    echo (string) $field->value;
                  }
            }
}
