在这个问题 Send attachments with PHP Mail()? 的帮助下 我用我的电子邮件解决了很多问题。 Gmail 显示带有在 HTML 中查看的图像的正确邮件，但在 Thunderbird 中它只显示图像而不显示 html。如果我检查邮件的源代码，它看起来也是正确的。
我能做什么？
$img_src = "km.png"; //about 79KB
$imgbinary = fread(fopen($img_src, "r"), filesize($img_src));
$img_str = base64_encode($imgbinary);
send("name@example.com", "Test Subject", $img_str);
function send($receiver, $subject, $content){
$header = "MIME-Version: 1.0" . "\n";
$header .= "Content-Type: multipart/mixed; boundary=\"aboundary\"" . "\n";
$header .= "--aboundary". "\n";
$header .= "Content-Type: multipart/alternative; boundary=\"xboundary\"". "\n\n";
$header .= "--xboundary". "\n".
"Content-Type: text/html; charset=utf-8". "\n".
"Content-Transfer-Encoding: 8bit". "\n";
$header .= "\n".
"<!DOCTYPE html><html><head><meta charset=\"utf-8\"><title></title></head><body>"."\n".
// "<h1>Hello World</h1><img src=\"cid:0123456789\" alt=\"no img\" /><p>Some Testcontent with umlauts ÖÄÜß</p>". "\n". //this shell work in step 2 as well
"<h1>Hello World</h1><img src=\"cid:0123456789\" alt=\"no img\" /><p>Some Testcontent without umlauts.</p>". "\n".
"</body></html>"."\n\n";
$header .= "--xboundary". "\n".
"Content-Type: image/png; name=\"att.png\"". "\n".
"Content-Disposition: inline; filename=\"att.png\"". "\n".
"Content-Transfer-Encoding: base64". "\n".
"Content-ID: <0123456789>". "\n".
"Content-Location: att.png". "\n".
"\n".
chunk_split($content, 64).
"\n".
"--xboundary--";
mail($receiver, $subject, "" , $header);
}
最佳答案
$img_src = "km.png"; //about 79KB
//$imgbinary = fread(fopen($img_src, "r"), filesize($img_src));
//$img_str = base64_encode($imgbinary);
$to= "name@example.com";
$subject = "Test Subject";
$headers = "From: youremail@somewhere.com \r\n";
$headers .= "Reply-To: youremail@somewhere.com \r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html" . "\r\n";
$headers .= "Content-Transfer-Encoding: base64" . "\r\n";
$message ="<html><head><title></title></head><body><h1>Hello World</h1><img src='".$img_src."' alt='no img' /><p>Some Testcontent with umlauts ÖÄÜß</p>
<h1>Hello World</h1><img src='".$img_src."' alt='no img' /><p>Some Testcontent without umlauts.</p>
</body></html>";
$base64contents = rtrim(chunk_split(base64_encode($message)));
$success = mail($to, $subject, $base64contents, $headers);
if (!$success){
echo "Something Went Wrong";}
