Can PHP Pass Anonymous Functions as Parameters?

Passing a Function as a Parameter in PHP

In PHP, the ability to accept a function as a parameter is enabled with the introduction of anonymous functions in PHP 5.3.0 and above. This opens up possibilities for more dynamic and modular programming.

Anonymous functions allow you to define a function without a name. They are often defined as lambda expressions, where you specify the parameters and the code to be executed. For example:

<code class="php">$anonFunc = function($parameter) {
    //some stuff to execute
};</code>
Copy after login

You can then pass this anonymous function as a parameter to another function:

<code class="php">function exampleMethod($anonFunc) {
    // execute anonymous function
    $anonFunc();
}</code>
Copy after login

When you call the exampleMethod function, the anonymous function you passed in will be executed within the function. This provides a flexible way to handle different scenarios or execute specific code based on input.
