What are the potential pitfalls of trying to retrieve variable names in PHP?

One potential pitfall of trying to retrieve variable names in PHP is that it can lead to overly complex and difficult-to-maintain code. Instead of relying on variable names, it is generally better practice to use associative arrays or objects to store related data. This approach can make your code more flexible and easier to understand. 

// Instead of trying to retrieve variable names, consider using associative arrays or objects
$person = [
    'name' => 'John',
    'age' => 30
];

echo $person['name']; // Output: John
echo $person['age']; // Output: 30
