HTML电子邮件中的PHP代码不起作用
[英]PHP code inside of HTML email not working
问题描述
Trying to test send a HTML email to myself using PHP but the PHP code inside the HTML does not work and I don't know why. 
尝试使用PHP向自己发送HTML电子邮件，但HTML内的PHP代码无法正常工作，我也不知道为什么。 Sorry if I'm not very clear, I'm quite new to this 抱歉，如果我不太清楚，我对此很陌生
<?php
$ccode = rand(1000, 9999);
$to = "example@gmail.com";
$from = "example2@gmail.com";
$subject = "Confirmation Code";
echo $ccode;
//begin of HTML message
$message = '<html>
<head>
<title> Confirmation Code</title>
</head>
<body style="background-color:#004d4d">
<div style= "text-align:center"> <img src="example.png" alt="Logo" width="300" height="300" align="top;center"> </div>
<h1 style="font-family:verdana; color:white; text-align:center"> This is your confirmation code: </h1>
<p style= "text-align:center;font-size:400%;color:#009999; font-family:arial">
<b>
//code that isn't working
<?php
$ccode = rand(1000, 9999);
echo $ccode;
?>
</b>
</p>
<p style= "text-align:center; font-family:verdana; color:white"> Please enter this code into the application. </p>
</body>
</html>';
//end of message
$headers = "From: $from\r\n";
$headers .= "Content-type: text/html\r\n";
// now lets send the email.
mail($to, $subject, $message, $headers);
echo "Message has been sent....!";
?>
The email sends as usual but the PHP part inside the email does not work and prints "$ccode" instead. 电子邮件照常发送，但是电子邮件中的PHP部分不起作用，而是显示“ $ ccode”。
I would appreciate any kind of help or advice on this thank you! 感谢您提供的任何帮助或建议！

$message = '<html>
...
</html>';
//end of message
This is a string, the code within is also considered text. 这是一个字符串，其中的代码也被视为文本。 You could declare your variable before assigning the string to $message. 您可以在将字符串分配给$ message之前声明变量。 Ie: 即：
<?php
$ccode = rand(1000, 9999);
$message = '<html>
<head>
<title> Confirmation Code</title>
</head>
<body style="background-color:#004d4d">
<div style= "text-align:center"> <img src="example.png" alt="Logo" width="300" height="300" align="top;center"> </div>
<h1 style="font-family:verdana; color:white; text-align:center"> This is your confirmation code: </h1>
<p style= "text-align:center;font-size:400%;color:#009999; font-family:arial">
<b>'.
$ccode .
'</b>
</p>
<p style= "text-align:center; font-family:verdana; color:white"> Please enter this code into the application. </p>
</body>
</html>';
//end of message

you can't put a code php when you try to declare the variable $message 当您尝试声明变量$ message时，您不能放置代码php
but you can do a concatenation with another variable which you have declared from the beginning 但是您可以与从一开始就声明的另一个变量进行串联
so you can either do this
<?php
$ccode = rand(1000, 9999);
$message = '<html> other balises' . $ccode . 'some other balises</html>';
?>
or with double cote (")
<?php
$ccode = rand(1000, 9999);
$message = "<html> other balises {$ccode} some other balises</html>";
?>
or the last solution
<?php
$message = "<html> other balises";
$ccode = rand(1000, 9999);
$message .= $ccode;
$message = "some other balises</html>";
?>

Problem come with your $message variable. 问题来自您的$message变量。
It's a string, so you can not use the open php block code here. 这是一个字符串，因此您不能在此处使用开放的php块代码。
It should be: 它应该是：
$message = '... <html code>' . $ccode . '... <other html code>';
