電子郵件中的圖像文件附件未通過PHP正確發送

我正在使用mail()函數來測試向自己發送帶有圖像文件附件的電子郵件。腳本的問題在於，當我查看電子郵件時，看到圖像應該存在的隨機數字，字母和符號的長牆。電子郵件中的圖像文件附件未通過PHP正確發送

請不要推薦PHPmailer或手動在郵件正文中添加圖片標籤。

我使用的主PHP文件：

<? 

include('init.php'); 

if (isset($_POST['name'], $_FILES['file'])){ 

    $body = <<<BODY 
    From: {$_POST['name']} 

    Details: 
     Name: {$_FILES['file']['name']} 
     Size: {$_FILES['file']['size']} 
     Type: {$_FILES['file']['type']} 

BODY; 

mail_file('[email protected]','[email protected]','a file upload',$body,$_FILES['file']); 
} 

?> 

<form action="" method="POST" enctype="multipart/form-data"> 
    <input type="text" name="name" id="name"> 
    <input type="file" name="file" id="file"> 
    <input type="submit" value="Email File"> 
</form>

的init.php：

<? 

$path = dirname(__FILE__); 
include("{$path}/mail.php"); 

?>

mail.php：電子郵件的

<? 

function mail_file($to, $from, $subject, $body, $file){ 
    $boundary = md5(rand()); 

    $headers = array(
     'MIME-Version: 1.0', 
     "Content-Type: multipart/mixed; boundary=\"{$boundary}\"", 
     "From: {$from}" 
    ); 

    $message = array(
     "--{$boundary}", 
     'Content-Type: text/html', 
     'Content-Transfer-Encoding: 7bit', 
     '', 
     chunk_split($body), 
     "--{$boundary}", 
     "Content-Type: {$file['type']}; name=\"{$file['name']}\"", 
     "Content-Disposition: attachment; name=\"{$file['name']}\"", 
     "Content-Transfer-Encoding: base64", 
     '', 
     chunk_split(base64_encode(file_get_contents($file['tmp_name']))), 
     "--{$boundary}--" 
    ); 

    mail($to, $subject, implode('\r\n', $message), implode('\r\n', $headers)); 
} 
?>

實例發送：

確定該內容類型是否正確發送？這可能是數據轉儲的原因。 –

另外您可能需要發送文件大小。 –

你可以發佈電子郵件的示例源嗎？代碼看起來不錯，但也許'郵件（）'搞亂東西 –

問題就出在這裏：

mail($to, $subject, implode('\r\n', $message), implode('\r\n', $headers));

已使用單引號，新行被視爲4系統字符的字符串\r\n，將其更改爲：

mail($to, $subject, implode("\r\n", $message), implode("\r\n", $headers));
