## Can Anonymous Functions Be Executed Immediately in PHP?

Instant Execution of Anonymous Functions in PHP

Question:

In JavaScript, anonymous functions can be defined and executed immediately:

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

Is there a similar approach available in PHP?

Answer:

Prior to PHP 7, executing anonymous functions immediately could be achieved using call_user_func():

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

However, in current PHP versions, you can directly execute anonymous functions:

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