CodeMirror: Is it possible to set up syntax highlighting without using PHP tags?

Question

PHP

Hello! Question for those who had experience with the CodeMirror (JavaScript) plugin. I need to make a PHP code editor with syntax highlighting, respectively, but there was such a problem in convenience. To make the highlighting work, you need to add a PHP tag before the code, as in this example:

<?php
echo "Hello, World!";

So the highlight will work as expected, but I would like to be able to write without tags, like this:
echo "Hello, World!";
Is it possible to configure this in CodeMirror or in some handler when receiving text, for example, add these tags automatically. Maybe someone faced similar? I turned all the official documentation, tried it in the search, but did not get any results. Thanks in advance for your support!

As a solution, insert the default opening tag:
<?php
