If your PHP parser is parsing your PHP tags in your HTML page then replace the < character with <. As far as showing code in HTML you can try putting it inside <code>..</code> — Drew

You can give the file a .phps extension, or use highlight_file() php.net/manual/en/function.highlight-file.php - If that'swhat this question is about. Or, are you asking to do a "printer-friendly" method? Your question is a bit unclear. — Funk Forty Niner

Thanks Fred for your reply. I am not looking for a printerfriendly version. I only want the code to be displayed as it is on a web page. — Debashis Sikdar

You're welcome. You can try either method I posted in my comment above. To call me out directly in order for me to get a notification, add the @ symbol followed by my name, should you need more info. — Funk Forty Niner

You can also use highlight_string() function

 <?php

 highlight_string("YOUR STRING/CODE GOES HERE");
 ?>

$gen_query_data= htmlspecialchars(' $'.$db_val_clean.'_ser = $_POST["'.$sel_name_clean.'_ser"];')."<br>";

     echo $gen_query_data;

please change your variables

if your server isn't set up to process .html for the php tag, you're fine to do exactly what you've done.

You can also use this: <?php which would render as <?php but not be seen by PHP.

One option you can use is PHP's highlight_file() function:

<?php
highlight_file("your_file.php");
?>

You can also use .html file extensions highlight_file("your_file.html").

Even a .txt file extension highlight_file("your_file.txt").

Consult:

this question is pretty old , but as long as no one used this solution so this would be helpful .

using htmlspecialchars :

htmlspecialchars — Convert special characters to HTML entities

echo htmlspecialchars("your special character goes here");
