[英]Empty message when sending zip file with PHP
**更新:更新了代碼並添加了Gmail中顯示的電子郵件內容。 **
我有一個問題想解決幾天。 但是,由於我一直無法取得任何進展,因此我需要其他人的幫助。 我正在嘗試將zip文件從服務器發送到電子郵件。 但是,電子郵件被發送為空。 這是代碼:
`$headers = "From: $from";
/* Generate boundary string */
$random = md5(time());
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random."\"";
/* Read the file */
$attachment = chunk_split(base64_encode(file_get_contents("backup-$date-$time-9.zip")));
/* Define body */
$message = "--PHP-mixed-$random
Content-Type: text/plain; charset=\"iso-8859-1\"
Attached, please find your backup file.
--PHP-mixed-$random
Content-Type: application/zip; name=backup-$date-$time-9.zip
Content-Transfer-Encoding: base64
Content-Disposition: attachment
$attachment
--PHP-mixed-$random--"; // no intendation
$mail = mail($email, $subject, $message, $headers);
echo $mail ? "Email sent<br>" : "Email sending failed<br>";`
感謝所有閱讀並希望對您有所幫助。

AAAAAA ==
--PHP-mixed-e44b531b0e0538185289abc521eda78d--
我通過以下更改使其正常工作:
From:
標頭中的空格字符,否則為無效標頭 boundary:
更改為boundary:
boundary=
$message
意圖,因為這似乎破壞了電子郵件。 邊界字符串--PHP-mixed-random
將電子郵件的不同部分分開,例如純文本,html文本,附件。 當邊界分隔符前面有空格時,它不再被解釋為分隔符,而是普通文本。 這是代碼:
<?php
$from = "xxx@myserver";
$email = "xxx@gmail.com";
$subject = "backup file";
$date = "29-11-2014";
$time = "1417275285"; // test file "backup-29-11-2014-1417275285-9.zip" in the same folder
$headers = "From: $from"; // remove space
/* Generate boundary string */
$random = md5(time());
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random."\""; // : to =
/* Read the file */
$attachment = chunk_split(base64_encode(file_get_contents("backup-$date-$time-9.zip")));
/* Define body */
$message = "--PHP-mixed-$random
Content-Type: text/plain; charset=\"iso-8859-1\"
Attached, please find your backup file.
--PHP-mixed-$random
Content-Type: application/zip; name=backup-$date-$time-9.zip

$attachment

$mail = mail($email, $subject, $message, $headers);
echo $mail ? "Email sent<br>" : "Email sending failed<br>";
