Php 获取附件-imap_fetchbody（）

如何获取电子邮件中的附件

代码 返回的附件甚至没有接近正确的文件大小，返回的数据如下所示

表示。我认为这会使代码变得复杂

你的问题是你没有得到你的编码数据

$body = imap_fetchbody($this->stream, $this->msgno, $part);
//$part=2 (first attachment file)
//$part=3 (second attachment file) ...

在你能在那个文件中得到你的真实数据之前，请看一下

$coding = $structure->parts[$part]->encoding;
if ($coding == 0) {
    $body = imap_7bit($body);
} elseif ($coding == 1) {
    $body= imap_8bit($body);
} elseif ($coding == 2) {
    $body = imap_binary($body);
} elseif ($coding == 3) {
    $body = imap_base64($body);
} elseif ($coding == 4) {
    $body = imap_qprint($body);
} elseif ($coding == 5) {
    $body = $body;
}

因此，您可以尝试将其打印出来：

echo $body;

注意：$section是文件的一部分。

你的问题是你没有得到你的编码数据

if ($coding == 0) {
    $body = imap_7bit($body);

} elseif ($coding == 4) {
    $body = imap_qprint($body);
