Passing Functions as Parameters in PHP

Manipulating functions as data elements is a versatile technique commonly employed in modern programming. One such example is passing functions as parameters, a feature not readily accessible in PHP versions prior to 5.3. Now, we delve into this capability, exploring when and how it can be utilized.

Question: Can functions be passed as parameters in PHP, similar to how they can be in JavaScript? For instance, consider the following JavaScript code:

object.exampleMethod(function() {
    // Logic to be executed
});

Answer: Yes, this became possible with the advent of PHP versions 5.3.0 and beyond. The PHP manual's documentation on Anonymous Functions provides a detailed description of this feature.

To implement this functionality in PHP, you would modify your exampleMethod as follows:

function exampleMethod($anonFunc) {
    // Execute the anonymous function
    $anonFunc();
}
