Are there any potential pitfalls to be aware of when using the unset function to remove elements from an array in PHP?

When using the unset function to remove elements from an array in PHP, it's important to be aware that the unset function will reset the array's keys. This can lead to unexpected behavior if you are relying on specific key-value pairs in the array. To avoid this pitfall, you can use array_splice to remove elements without resetting the keys.

// Example of using array_splice to remove elements without resetting keys
$array = [1, 2, 3, 4, 5];
$index = 2; // Index of element to remove
array_splice($array, $index, 1);
print_r($array); // Output: [1, 2, 4, 5]
