How to Dynamically Access PHP Class Properties Using String Values?

Dynamically Accessing PHP Class Properties with Strings

In PHP, accessing a class property directly through an object's arrow operator is a common practice. However, there may be instances when you want to dynamically access a property based on a string value, such as in the example provided:

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

To achieve this dynamically, you can utilize the following approaches:

Using Dynamic Variable Name

$prop = 'Name';

echo $obj->$prop;

This method involves dynamically creating a variable name using the string value. Accessing the class property becomes equivalent to standard direct access.

Using ArrayAccess Interface

If you have control over the class definition, you can implement the ArrayAccess interface to access class properties like array elements:

echo $obj['Name'];

With this approach, the class property becomes accessible using array-style syntax, allowing you to use string values as property names.
