Are there any potential pitfalls when using unset() to remove elements from an array in PHP?

When using `unset()` to remove elements from an array in PHP, one potential pitfall is that it will reset the array's keys. This can lead to unexpected behavior if your code relies on specific key-value pairs. To avoid this issue, you can use `array_splice()` instead, which will remove elements without resetting the keys. 

// Original array
$array = ['a' => 1, 'b' => 2, 'c' => 3];

// Remove element 'b' without resetting keys
array_splice($array, array_search('b', array_keys($array)), 1);

// Output updated array
print_r($array);
