How to add inline PHP to a .twig file?
Question
I am trying to modify the <body> tag in a .twig file.
The body tag looks like this...
<body{{ body_id is not empty ? ' id=' ~ body_id }} >
...and I want to add...
class="<?php echo basename($_SERVER['PHP_SELF'], '.php'); ?>-page"
But when I do so I end up with this mess:
<body id="foo" class="<?php echo basename($_SERVER['PHP_SELF'], '.php'); ?>-page">
In short, how can I add inline PHP to a .twig file?

Twig won't interpret PHP - it doesn't understand what it means.
A better way of doing this is to pass the result of basename($_SERVER['PHP_SELF'], '.php' into the twig context from whatever PHP script you call the template.
Assuming you call the context var body_classes you can then update the template to something like this:
<body{{ body_id is not empty ? ' id=' ~ body_id }}{{ body_classes is not empty ? ' class=' ~ body_classes }} >
Edit: While this approach may seem counterintuitive at first it gives you the benefit of separating logic and presentation.
