Как получить значения из stdClass в PHP?

Question

Я работаю над своим php для поиска значений в массиве stdClass.Мне трудно получить значения из массива, потому что он не будет извлекать значения и сохранять их в массиве $body_attachment, когда я попытался использовать ifdisposition и disposition == 'inline' для поиска значений, которые я хочу.

Когда я попробовал это:

if (($structure->parts[$i]->ifdisposition) && ($structure->parts[$i]->disposition == 'inline')) {

    foreach($structure->parts[$i]->parameters as $object) {
        if(strtolower($object->attribute) == 'name') {
           $body_attachments[$body_number]['is_attachment'] = true;
           $body_attachments[$body_number]['name'] = $object->value;
        }
    }
    $body_number++;
}

Будет выводиться так:

Это должно быть:

[1] => stdClass Object 
( 
    [type] => 5 
    [encoding] => 3 
    [ifsubtype] => 1 
    [subtype] => PNG 
    [ifdescription] => 0 
    [ifid] => 1 
    [id] => 
    [bytes] => 29154 
    [ifdisposition] => 1 
    [disposition] => inline 
    [ifdparameters] => 1 
    [dparameters] => Array 
                   ( 
                       [0] => stdClass Object 
                       ( 
                            [attribute] => filename 
                            [value] => what-is-bootstrap.png 
                       ) 
                   ) 
    [ifparameters] => 1 
    [parameters] => Array 
                  ( 
                      [0] => stdClass Object 
                      ( 
                          [attribute] => name 
                          [value] => what-is-bootstrap.png 
                      ) 
                  ) 
 )

Однако я пробовал это:

$body_attachments[$body_number] = array();

if (($structure->parts[$i]->disposition === 'inline')) {
    ...etc
}

А также я попробовал это:

if (($structure->parts[$i]->ifdisposition) && ($structure->parts[$i]->disposition == 'inline')) {
 ...etc
}

Это не будет иметь никакого значения.Он не будет выводить значения из stdClass, где у него есть значение с именем inline.

Вот полный код:

<?php

require_once "Mail.php";
require_once('Mail/IMAPv2.php');

$username = 'username';
$password = 'password';
$mailserver = '{imap.example.com:993/imap/ssl/novalidate-cert}INBOX';
$mailbox = imap_open($mailserver, $username, $password) or die("Can't connect: " . imap_last_error());
$key = "mykey";
$email_number = openssl_decrypt(hex2bin($_GET['id']),'AES-128-CBC', $key);

$structure = imap_fetchstructure($mailbox, $email_number);
$body_attachments = array();
$body_number = 0;

for($i = 0; $i < count($structure->parts); $i++) {

    if (($structure->parts[$i]->ifdisposition) && ($structure->parts[$i]->disposition === 'inline')) {

        foreach($structure->parts[$i]->parameters as $object) {
            if(strtolower($object->attribute) == 'name') {
                $body_attachments[$body_number]['is_attachment'] = true;
                $body_attachments[$body_number]['name'] = $object->value;
             }
         }
     }
     $body_number++;
 }
 ?>

То, что я пытаюсь сделать, это я хочунайдите значение inline в массиве stdClass, затем я хочу получить значение what-is-bootstrap.png, чтобы сохранить его в массиве $body_attachment.

Не могли бы вы показать мне пример того, как я могу получитьзначение из массива stdClass, когда я хочу найти inline' для извлечения значения what-is-bootstrap.png для хранения в массиве $body_attachment?

Спасибо.

Answer 1

Использование json_decode (json_encode (), true) для упрощения объекта stdclass до ассоциативного массива, поскольку иногда бывает сложно работать с несколькими смешанными объектами и массивами в одной переменной.

Я просто взял фрагмент кода в этой части оператора условия и цикла, чтобы сделать пример

if (($structure->parts[$i]->ifdisposition) && (strtolower($structure->parts[$i]->disposition) === 'inline')) 
{

Вот единственная часть, которую я преобразовал, используя json_decode (json_encode ($ stdclass), true)

Преобразует объект stdclass в ассоциативные массивы

    $parameters = json_decode(json_encode($structure->parts[$i]->parameters), true);
    for($i =0; $i < count($parameters); $i++) 
    {
        if(strtolower($parameters[$i]['attribute']) === 'name') {
            $body_attachments[$body_number]['is_attachment'] = true;
            $body_attachments[$body_number]['name'] = $parameters[$i]['name'];
         }
    }

Конец цикла

}

Вы можете изменить операторы цикла с поддержки объектов на массив, если хотите преобразовать весь объект в ассоциативный массив

вы также можете использовать эту функцию get_object_vars () она также преобразует объект в массив, но они отличаются от json_decode с точки зрения глубокого, я попробовал их обоих, get_object_vars () преобразует только родительский объект, а не значения субобъекта

 $parameters = (object) array('0' => 
                  (object) array("attribute"=> "name", "value"=>"what-is-bootstrap.png" )
                  );

  print_r($parameters);
  print_r(json_decode(json_encode($parameters), true));
  print_r(get_object_vars($parameters));

и результаты

stdClass Object
(
    [0] => stdClass Object
    (
        [attribute] => name
        [value] => what-is-bootstrap.png
    )
 )

 Array
(
    [0] => Array
    (
        [attribute] => name
        [value] => what-is-bootstrap.png
    )
 )

Array
(
    [0] => stdClass Object
    (
        [attribute] => name
        [value] => what-is-bootstrap.png
    )
)

Вклады пользователей в документации показывают, что значение равно INLINE, а не inline. Рекомендуется выполнять сравнение без учета регистра.

if ($structure->parts[$i]->ifdisposition && strtolower($structure->parts[$i]->disposition) == 'inline') {
