Changing file extension to .php doesn't seem to support PHP tags

[JohnnyWalkerDigital]

Bug description

v5.50.0

According to the documentation, if you change your view's file extension from .antlers.html to .antlers.php you can write all the raw PHP you want using native PHP tags. However I tried this with a view and the PHP tags within the document are rendered as HTML.

For example:

<?php
  if (!isset($_GET["new"])) {
?>

is in the HTML output as

<!--?php
  if (!isset($_GET["new"])) {
?-->

How to reproduce

1. Change file extension of a view from .antlers.html to .antlers.php
2. Add <?php ?> tags to the beginning of the file
3. Preview the output in your browser

Hmm, your code is working fine for me (provided I add a closing <?php } ?> somewhere). How are you using the .antlers.php file - as a layout/template/partial?

While you can use raw PHP in Antlers templates like that, for something simple like checking a GET parameter, I'd use Statamic's get variable instead:

{{ if !get:new }}
    Your code here...
{{ /if }}
