In what scenarios would using array_splice() be more appropriate than array_slice() for modifying arrays in PHP?

array_splice() would be more appropriate than array_slice() when you want to modify the original array by removing elements and possibly inserting new elements at the same time. This function allows you to specify the start index, number of elements to remove, and optional elements to insert, all in one function call. 

// Example of using array_splice() to remove elements and insert new elements in an array
$originalArray = [1, 2, 3, 4, 5];
$newElements = ['a', 'b'];

// Remove 2 elements starting from index 1 and insert new elements
array_splice($originalArray, 1, 2, $newElements);

print_r($originalArray); // Output: [1, 'a', 'b', 4, 5]
