What are the advantages and disadvantages of using array_splice() in PHP when manipulating arrays?

When manipulating arrays in PHP, array_splice() can be a useful function to add or remove elements from an array at a specified index. However, there are some advantages and disadvantages to consider. Advantages: 1. It allows for easy insertion or deletion of elements at specific positions in an array. 2. It can be more efficient than manually manipulating arrays using loops. 3. It maintains the keys of the array after insertion or deletion. Disadvantages: 1. It modifies the original array in place, which may not be desired in some cases. 2. It can be less intuitive to use compared to other array manipulation functions. 3. It may not be suitable for large arrays or complex manipulations.

// Example of using array_splice() to insert an element at a specific index
$originalArray = [1, 2, 3, 4, 5];
$insertedElement = 'inserted';
$index = 2;

array_splice($originalArray, $index, 0, $insertedElement);

print_r($originalArray); // Output: [1, 2, 'inserted', 3, 4, 5]
