【问题描述】：
我正在使用我的 php 来搜索 stdClass 数组中的值。我很难从数组中获取值，因为当我尝试使用ifdisposition 和disposition == 'inline' 搜索我想要的值时，它不会获取值并存储在$body_attachment 数组中。
当我尝试这个时：
if (($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++;
}
会这样输出：

应该是：
[1] => stdClass Object
(
[type] => 5
[encoding] => 3
[ifsubtype] => 1
[subtype] => PNG
[ifdescription] => 0
[ifid] => 1
[id] =>

[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
)
)
)
不过我已经试过了：
$body_attachments[$body_number] = array();
if (($structure->parts[$i]->disposition === 'inline')) {
...etc
}
我也试过这个：
if (($structure->parts[$i]->ifdisposition) && ($structure->parts[$i]->disposition == 'inline')) {
...etc
}
不会有任何区别。它不会输出 stdClass 中的值，它有一个名为 inline 的值。
这里是完整的代码：
<?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++;
}
?>
我想要做的是我想从 stdClass 数组中搜索值 inline，然后我想获取值 what-is-bootstrap.png 以将其存储在 $body_attachment 数组中。
当我想搜索inline' 以获取what-is-bootstrap.png 的值以存储在$body_attachment 数组中时，您能否告诉我一个示例如何从stdClass 数组中获取值？
谢谢。

【问题讨论】：
-
您提到的第一个输出属于哪个变量？您需要
$body_attachments中的其余值还是只需要“内联”值？ -
@HTMHell 那么这属于变量
$structure->parts[$i]。我想将值what-is-bootstrap.png存储在body_attachments中与inline值在同一行中。有意义吗？ -
您的代码无法到达
if的什么地方？=== 'inline'或== 'name'? -
@HTMHell 它不会将值
what-is-bootstrap.png存储在$body_attachments数组中。 -
@chris oojer，抱歉我的错误，array_values 不适合这个，我将使用 json_decode, true) 来发布我的答案
