Can PHP Anonymous Functions Be Executed Immediately Like in JavaScript?

Executing Anonymous Functions Immediately in PHP

In JavaScript, developers can create and execute anonymous functions directly within parentheses:

<code class="javascript">(function () { /* do something */ })()</code>

Can PHP programmers replicate this functionality?

PHP Pre-v7.0 Approach

Prior to PHP 7.0, the recommended method for immediate execution involved the call_user_func function:

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

PHP 7.0 Syntax

From PHP 7.0 onward, developers gained the ability to execute anonymous functions simply by adding parentheses:

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

This syntax provides a more concise and intuitive way of executing anonymous functions immediately in PHP.
