那么,我做错了什么
谢谢 你最好使用或我想你会发现使用类似PHPMailer的东西更容易试试这个来编码你的文件以便传输 更换线路:
$file = chunk_split(base64_encode($file));
与:
希望您已经尝试过(注意边界的拼写):
斯威夫特·梅勒看起来不错,但是,这个建议是为了提高我的PHP技能,所以我想知道我做错了什么,这样我可以改进它。你可以查看他们的来源,他们有方便的方法来添加各种附件。这些代码似乎只是将附件放在消息文本中。请参阅PEAR项目中的Mail_Mime类,谢谢,我已经解决了这个问题,但我仍然有相同的问题。
//Encode the file for transit
$content = '';
$fp = fopen($att_path, 'r');
do {
$data = fread($fp, 8192);
if (strlen($data) == 0) break;
$content .= $data;
} while (true);
$file = chunk_split(base64_encode($content));
$str = "==Multipart_Boumdary_x{$num}x";
$str = "==Multipart_Boundary_x{$num}x";
