Is it safe to use $_SERVER['PHP_SELF'] outside a form or link?

Hi,

I'm new to PHP and I was wondering if it's perfectly safe to use $_SERVER['PHP_SELF'] like so:

<body<?php  if(basename($_SERVER['PHP_SELF']) ==  'home.php') echo  ' class="home"'; ?>>
…
</body>

As far as I understand, the $_SERVER['PHP_SELF'] variable can only be exploited when used as a link or in a form/inputs, where the variable should be wrapped into htmlspecialchars() to counter XSS attacks, am I right?

There's no security issue there because the only thing that can be "hacked" is whether the body element has a class attribute or not.

Thank you to confirm my thoughts. I had a doubt after I stumbled upon an old thread on stackoverflow where a guy implied this kind of code was possibly flawed.
