Running Anonymous Functions on the Spot: A Comparison of JavaScript and PHP

In JavaScript, anonymous functions can be instantly executed using notation like this:

(function () { /* do something */ })()

But can we do the same in PHP?

For PHP versions before 7, there was only one obvious way to trigger immediate function execution, as illustrated here:

<code class="php">call_user_func(function() { echo 'executed'; });</code>

<code class="php">(function() { echo 'executed'; })();</code>

This syntax allows us to create and execute an anonymous function in one succinct line.
