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 时，它不会获取值并将其存储在 来搜索我想要的值。$body_attachment 数组中disposition == 'inline'
当我尝试这样做时:
if (($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++;
}
输出结果如下:

不过我试过这个:
$body_attachments[$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
}
这不会有任何区别。它不会输出来自 stdClass 的值，其中它有一个名为 inline 的值。
完整代码如下:
<?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 将其存储在 $body_attachment 数组中。
当我想搜索 inline' 来获取 what-is-bootstrap.png 的值时，你能给我举个例子吗？ 存储在 $body_attachment 数组中？
谢谢。

最佳答案
使用 json_decode(json_encode(), true) 将 stdclass 对象简化为关联数组，因为有时在单个变量中处理多个混合对象和数组会很复杂。
这部分条件和循环语句我只是拿了一段代码来做个例子
if (($structure->parts[$i]->ifdisposition) && (strtolower($structure->parts[$i]->disposition) === 'inline'))
{
Here is the only part I converted using json_decode(json_encode( $stdclass ),true)
It converts the stdclass object into associative arrays
$parameters = json_decode(json_encode($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'];
}
}
循环结束
}
如果要将整个对象转换为关联数组，可以将循环语句从对象支持更改为数组
你也可以使用这个函数 get_object_vars( ) 它也可以将对象转换为数组，但是它们与 json_decode 的深度不同我都试过了， get_object_vars( ) 只转换父对象不转换子对象值
$parameters = (object) array('0' =>
(object) array("attribute"=> "name", "value"=>"what-is-bootstrap.png" )
);
print_r($parameters);
print_r(json_decode(json_encode($parameters), true));
print_r(get_object_vars($parameters));
结果是
stdClass Object

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