How to Access PHP Class Properties Dynamically Using Strings?

Obtaining PHP Class Property using a String:

In PHP, when you need to retrieve a property within a class, you typically use the arrow operator (->). However, sometimes you may require a more flexible approach where you dynamically obtain the property name as a string. This article explores how to achieve this dynamic property retrieval.

The "magic" function referenced in the question introduces this dynamic behavior, enabling the syntax:

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

To implement this functionality, you can use the following technique:

$prop = 'Name';

echo $obj->$prop;

This approach works by assigning the desired property name to a variable and then accessing the property using that variable.

If you have control over the class definition, another option is to implement the ArrayAccess interface, which allows you to access class properties using array syntax:

echo $obj['Name'];

This method provides a convenient and consistent approach to retrieving class properties regardless of whether you know the property name at compile time. It also enhances code readability and maintainability.
