Laravel’s transform() Method: A Modern Approach to Data Transformation

When handling conditional data modifications in Laravel applications, the transform() helper is a versatile and efficient tool. It streamlines data transformations by selectively processing values while gracefully managing null cases. Let’s explore how this helper can elevate your data workflows.

1. Value: The data you want to transform.
