PHP电子邮件附件不会存储在已发送的文件夹中

Question

I am working on PHP to store the emails in the sent folder. I have got a problem with store the attachments in the sent folder because the attachment will not store in the sent folder as only the email message that will store in the sent folder.

Output for $attachment :

Here is the full code:

<?php

$dmy=date("d-M-Y H:i:s"); 
$dmy.= " +0200"; // Had to do this bit manually as server and me are in different timezones 

$username = 'myusername';
$password = 'mypassword';

$mailserver = '{imap.example.com:993/imap/ssl/novalidate-cert}INBOX.Sent';
$mailbox = imap_open($mailserver, $username, $password);
$messageID = sprintf("<%s.%s@%s>",
    base_convert(microtime(), 10, 36),
    base_convert(bin2hex(openssl_random_pseudo_bytes(8)), 16, 36),
    'example.com');

$boundary = "------=".md5(uniqid(rand())); 
$header = "MIME-Version: 1.0 "; 
$header .= "Content-Type: multipart/mixed; boundary=".$boundary; 
$header .= " "; 
$file = "uploads/add-attachment.png"; 
$filename = "add-attachment.png"; 
$ouv = fopen ("$file", "rb");
$lir = fread ($ouv, filesize ("$file"));
fclose($ouv); 

$attachment = chunk_split(base64_encode($lir)); 

$msg2 .= "--$boundary "; 
$msg2 .= "Content-Transfer-Encoding: base64 "; 
$msg2 .= "Content-Disposition: attachment; filename=\"$filename\"\r\n" ;
$msg2 .=  "\r\n" . $attachment . "\r\n"; 
$msg2 .= "\r\n\r\n\r\n"; 
$msg2 .= "--$boundary--\r\n\r\n"; 
$msg2 .= " "; 
$msg3 .= "--$boundary-- "; 
imap_append($mailbox, $mailserver,

    "From: rob@example.com r\n".
    "To: ddsgds@gmail.com \r\n".
    "Subject: This is the subject \r\n".
    "Date: ".date("r", strtotime("now"))."\r\n".
    "Message-ID: ".$messageID."\r\n".
    "MIME-Version: 1.0 \r\n".
    "Content-Type: multipart/mixed; boundary=".$boundary.
    "Content-Transfer-Encoding: 7bit \r\n".
    "\r\n\r\n".
    $msg2.
    $msg3,
    "\\Seen"
    );
imap_close ($mailbox);

echo "message have been stored in the sent folder, now let check";
echo "<br>";
?>

I am unable to find out why the email attachments did not store in the sent folder. I have checked the file location and I have put the correct file location. I have also checked the file name, the variable $attachment and everything I have put are correct so nothing have to do with it. I might have miss something but I am not sure what.

Can you please show me an example how I can be able to store the email attachments in the sent folder?

Thank you.

You aren't storing the attachment anywhere cause you only read the existing file and closing reading. If you want to write somehere the $attachment variable you need to use something like this:

$write_file = fopen('new_file.txt', 'w');
fwrite($write_file, $attachment);
