附件不是用php发送的吗？

此代码将html文件作为附件发送，工作正常。 但是在下一个代码片段中，当我将附件添加到图像时，它没有被发送。为什么会这样

<?php
$file_path = "file.html"; // server path where file is placed
$file_path_type = "text/html"; // File Type
$file_path_name = "newfilename.html"; // this file name will be used at reciever end 

$from = "xyz@gmail.com"; // E-mail address of sender
$to = "abc@gmail.com"; // E-mail address of reciever
$subject = "Please check the Attachment."; // Subject of email
$message = "This is the message body.&lt;br&gt;&lt;br&gt;Thank You!&lt;br&gt;&lt;a href='http://7tech.co.in'&gt;7tech.co.in Team&lt;/a&gt;"; 

$headers = "From: ".$from; 

$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file); 

$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x"; 

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\""; 

$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n"; 

$data = chunk_split(base64_encode($data)); 

$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";  

if(@mail($to, $subject, $message, $headers)) {
echo "File send!";

} else {
echo 'Failed';
}
?>

咨询

当然，您可以继续使用您的手工邮件构造代码。但是，请不要将额外的调试工作卸载到其他人身上。你的选择，你的问题

如果你稍微聪明一点，使用一个现有的解决方案而不是带帮助代码。
你收到了什么错误？一个问题，虽然可能不相关，但正在走向尾端：<代码> $DATA.=“\\N\N”……/代码>不应该有等号，所以：<代码> $DATA。“\n\n”[…]

@fredrik我收到的消息是失败的！不，那是你打印的。

mail

怎么说？真的没有理由自己编写这些东西。几乎是PHP中邮寄的黄金标准。有易于使用、经过良好测试的库可以为您完成所有这些。请不要告诉我这是不可能的。请告诉我错误。我希望以这种方式学习。我可能稍后使用phpmailer或swift！但是这段代码有什么错误@用户2280276当然有可能。但你可以先自己筛选。你还没有这么做。这可能没有什么帮助，因为它们都太本地化了，就像你的问题一样。
