Oct 25, 2024 am 01:08 AMExecuting 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.
