我想要表单输入中的"name"(http://besthomebuildercoloradosprings.com/)显示在自动回复电子邮件中（在单词"祝贺"之后）。尽管插入了<?php echo $name; ?>，但它目前没有显示在我的html中。我浏览了所有的论坛并进行了实验，但没有任何效果。
以下是我的webformmailer.php文件的内容：
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$bonus = $_POST['bonus'];
$formcontent=" Hello, 'n 'nThis email has been sent to you from the Challenger Homes BestHomeBuilderColoradoSprings.com contact form. 'n 'n From: $name 'n Phone: $phone 'n Email: $email 'n Bonus: $bonus 'n";
$recipient = "sally@superfinedesigns.com";
$subject = "New lead from Challenger Homes!";
$mailheader = "From: sally@superfinedesigns.com 'r'n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
header("Location: http://www.besthomebuildercoloradosprings.com/thankyou.html");
$headers = 'MIME-Version: 1.0' . "'r'n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "'r'n";
@mail($email, $email_subject, $replymsg, $headers);
$replymsg = "

在您的案例中，<?php echo $name; ?>在PHP中使用PHP。这没有道理：
<?php
$name = "test";
$replymsg = "<?php echo $name; ?>";
最好简单使用{$name}:
<?php
$name = "test";
$replymsg = "Blah blah {$name} and more.";
或者使用字符串串联：
<?php
$name = "test";
$replymsg = "Blah blah " . $name . " and more.";
该标记位于双引号的PHP文本字符串中，因此您根本不需要标记。双引号字符串中的变量会自动插入。只要把<?php echo $name; ?>换成$name，你就会好起来。
