This repository demonstrates a subtle issue with PHP's isset() function. The isset() function is often used to check if a variable is set and is not NULL. However, its behavior can be surprising when dealing with empty strings ('') or empty arrays ([]).
The bug.php file contains code that exhibits this unexpected behavior. The bugSolution.php file shows a corrected version that addresses the issue.
This example highlights the importance of carefully considering the different cases when using isset() and the need for potentially more robust checks.
