Question

我发现这段代码效果不错，但我需要它：

1。（必须）将附件保存到服务器上的特定文件夹，而不是.php文件所在的位置。

2。（如果可能）现在代码生成一些零字节大小的文件。（我可以编写一些检查文件大小的内容，然后删除大小为零的文件，但如果可能的话，我想首先禁止它被创建。

 <?php

    function getFileExtension($fileName){
       $parts=explode(".",$fileName);
       return $parts[count($parts)-1];
    }

    $imap = imap_open($server, $username, $password) or die("imap connection error");
    $message_count = imap_num_msg($imap);
    for ($m = 1; $m <= $message_count; ++$m){

        $header = imap_header($imap, $m);
        //print_r($header);

        $email[$m]['from'] = $header->from[0]->mailbox.'@'.$header->from[0]->host;
        $email[$m]['fromaddress'] = $header->from[0]->personal;
        $email[$m]['to'] = $header->to[0]->mailbox;
        $email[$m]['subject'] = $header->subject;
        $email[$m]['message_id'] = $header->message_id;
        $email[$m]['date'] = $header->udate;

        $from = $email[$m]['fromaddress'];
        $from_email = $email[$m]['from'];
        $to = $email[$m]['to'];

Answer 1

您可以将文件写入您喜欢的任何文件夹，rename()功能可用于此目的

http://php.net/manual/en/function.rename.php

rename('image1.jpg', 'del/image1.jpg');

如果您想将现有文件保留在同一位置，则应使用复制

http://php.net/manual/en/function.copy.php

copy('image1.jpg', 'del/image1.jpg');

您可以在put_file_contents()之后使用代码在目录/文件夹

周围移动文件

编辑：在另一个目录中创建文件，而不是在创建后移动它

file_put_contents('./myDir/myFile', $file);

.表示项目的当前目录。

此外，请记住file_put_contents()不会创建他们需要存在的文件夹/目录，或者您需要使用mkdir()

创建它们

Answer 2

替换

download_file = self.bucket.download_file(kch_file_to_be_downloaded_key, destination_of_kch_file_to_be_downloaded)

使用

foreach ($attachments as $key => $attachment) {
            $name = $attachment['name'];
            $contents = $attachment['attachment'];
            file_put_contents($name, $contents);
}

它会将您的附件保存到您的根目录，您可以从那里随意移动它。

Answer 3

您可以将文件直接放在所需的路径上，如下所示：

$mypath = '../../myfiles/';
foreach ($attachments as $attachment) {
           file_put_contents( $mypath . $attachment['name'], $attachment['attachment']);
 }
