What is the purpose of the php array_reverse function?

array_reverse() is a PHP array function that reverses the order of elements in an array. This function returns a new array containing the elements from the original array, but in reverse order.

Specifically, the purpose of array_reverse() includes:

1. Reverse the order of the array: rearrange the elements of the original array in reverse order, meaning the first element of the original array becomes the last element of the new array, the last element of the original array becomes the first element of the new array, and so on.
2. Maintain key-value association: If the original array is an associative array (in the form of key-value pairs), array_reverse() will reverse the order of elements while preserving the association between keys and values, ensuring that the new array remains an associative array.
3. Using array_reverse() does not alter the original array itself; instead, it returns a new array with the reversed order, while the original array remains unchanged.

The array_reverse() function makes it easy to reverse the order of elements in an array, which is useful for cases where you need to process the array in reverse, such as printing a list in reverse order or generating a reversed arrangement of elements.
