How Can I Access PHP Class Properties Dynamically Using Strings?

Manipulating PHP Class Properties Dynamically

Obtaining a property from a PHP class using a string instead of its explicit name is a valuable technique for dynamic property access. How do we achieve this "magic"?

Let's explore a scenario:

$obj->Name = 'something';
$get = $obj->Name;

can be written as:

magic($obj, 'Name', 'something');
$get = magic($obj, 'Name');

Solution 1: Leveraging the Variable Variable Syntax

To dynamically access a property, we can use the variable variable syntax:

<?php

$prop = 'Name';

echo $obj->$prop;

This dynamically accesses the 'Name' property of the $obj object.

Solution 2: Implementing the ArrayAccess Interface (Optional)

If the class has control, implementing the ArrayAccess interface allows access to properties using array syntax:

echo $obj['Name'];

This provides a convenient and flexible method for accessing class properties dynamically.
