Syntax error, unexpected T_SL
提问by Lance
I'm fairly new to php and I'm using a script that creates a function called the "mime_mailer" which essentially allows me to use PHP to send emails that are able to be designed with CSS instead of being merely plain text.
我对 php 还很陌生，我正在使用一个脚本来创建一个名为“mime_mailer”的函数，它基本上允许我使用 PHP 发送能够用 CSS 设计的电子邮件，而不仅仅是纯文本。
Yet, in my registration script, I try to write some code that sends a CSS email, but I get an error saying that there's a syntax error. Could someone please fill me in on this?
然而，在我的注册脚本中，我尝试编写一些发送 CSS 电子邮件的代码，但我收到一条错误消息，指出存在语法错误。有人可以帮我补充一下吗？
$subject = "Your Red-line Account";
$css = "body{ color: #090127; background-color: #f0f0f0; }";
$to = $usercheck;
//Message
$message =<<<END
<html>
<head>
<title>
Red-line
</title>
</head>
<body>
<p>
Hi $first_name,
</p>
<p>
Your Red-line account is almost complete. To finish, go to <a href='www.thered-line.com'>The Red-line</a> and enter your eight digit confirmation code.
</p>
<p>
Your confirmation code is: <b>$code</b>
</p>
<p>
Sincerely,
</p> <br />
<p>
The Red-line Operator
</p>
</body>
</html>
END;
// To send HTML mail, the Content-type header must be set
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
// Additional headers
$headers .= "From: The Red-line <[email protected]>\r\n";
$headers .= "To: $first_name $last_name <$usercheck>\r\n";
// Mail it
require_once("function_mime_mailer.php");
mime_mailer($to, $subject, $message, $headers, NULL, $css);
}
Here is the code for the "function_mime_mailer.php" file.
这是“function_mime_mailer.php”文件的代码。

Just had the same problem.
刚刚有同样的问题。
Turned out to be content on the same line as my opening HERDEOC
结果和我的开场HERDEOC在同一条线上
wrong example
错误的例子
echo <<<HEREDOC code started on this line
HEREDOC;
correct example
正确的例子
echo <<<HEREDOC
code should have started on this line
HEREDOC;
Hope this helps someone else!
希望这对其他人有帮助！

Have a look at the List of Parser tokens.
查看解析器令牌列表。
T_SLreferences to <<.
T_SL引用<<.
You should not use tabs or spaces before you use END;. Have a look at this huge warning.
在使用之前，不应使用制表符或空格END;。看看这个巨大的警告。

A side note, but might well help someone: a bad git merge can cause this. Consider:
旁注，但可能对某人有所帮助：错误的 git merge 可能会导致这种情况。考虑：
function foo
<<<<<<< HEAD
$bar = 1;
<<<<<<< e0f2213bc34d43ef
$bar = 2;
The PHP parser would produce the same error.
PHP 解析器会产生同样的错误。

It had the same exact same issue but mine was because I had whitespace at the end of my heredoc on the top line:
它有完全相同的问题，但我的问题是因为我的heredoc末尾有空格：
$var = <<< HTML(whitespaces here caused the error)
stuff in here
HTML;
HTML;

What version of php are you using? The nowdoc syntax is only valid since PHP 5.3.0. See the manual: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc
你用的是什么版本的php？nowdoc 语法仅自 PHP 5.3.0 起有效。请参阅手册：http: //www.php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc

There is a bug in function_mime_mailer.php:
function_mime_mailer.php 中有一个错误：
if(empty($headers)){
$headers = "MIME-Version: 1.0\n";
}else{
$headers.= "\nMIME-Version: 1.0\n";
}
should be
应该
if(empty($headers)){
$headers = "MIME-Version: 1.0\r\n";
}else{
$headers.= "\r\nMIME-Version: 1.0\r\n";
}
also, if you include the MIME-Version header, then the function will include it once more - effectively having two of them.
此外，如果您包含 MIME-Version 标头，则该函数将再次包含它 - 实际上有两个。
