Are there any potential pitfalls to be aware of when reordering keys in an array in PHP?

When reordering keys in an array in PHP, one potential pitfall to be aware of is that the reordering may affect the functionality of any existing code that relies on specific key-value associations. To avoid this issue, you can use the `array_values()` function to reindex the array numerically without changing the order of the elements. 

// Original array with keys to be reordered
$array = array(
    'a' => 'Apple',
    'b' => 'Banana',
    'c' => 'Cherry'
);

// Reorder keys numerically without changing element order
$array = array_values($array);

// Output the reordered array
print_r($array);
