Anonymous Self-Executing Functions in JavaScript and PHP

I’ve used the anonymous self-executing paradigm a few times in JavaScript over the years. Something like this:

(function() {
  console.log('So running. Much anonymous.');
})();

Then I started thinking - can I do the same thing in PHP (not a question of should, a question of can!) Turns out, you can still do it - just a different method of self-execution is required:

<?php
call_user_func(function() {
  print "Oy - even PHP!";
});

That’s it for today!
