Is this WordPress code? This is so wrong.

<html> 
<title> Welcome page </title> 
<body> 
<?php echo "<h2>Your Input:</h2>"; ?> 
Your Name: 
<?php echo $_POST["name"]; ?> 
<br><br> Your email address: 
<?php echo $_POST["email"]; ?> 
<br><br> Your website: 
<?php echo $_POST["website"]; ?> 
<br><br> Comment: 
<?php echo $_POST["comment"]; ?> 
<br><br> Gender: 
<?php echo $_POST["gender"]; ?> 
<br><br> 
<button onclick="history.back()">Submit another response</button> 
</body> </html>

This is the way it should be done. Do not switch back and forth between PHP and HTML mode.

$name = $_POST["name"];
$gender = $_POST["gender"];
$comment = $_POST["comment"];
$website = $_POST["website"];
echo <<<EOT
<html> 
<title> Welcome page </title> 
<body> 
<h2>Your Input:</h2>
Your Name: $name
<br><br> Your email address: $email
<br><br> Your website: $website
<br><br> Comment: $comment
<br><br> Gender: $gender
<br><br> 
<button onclick="history.back()">Submit another response</button> 
</body> </html>
