There are 2 new functions on functions-online.com! You can now execute and test array_splice and array_values as you like.
Additionally arrays are now supported in a wider range and do not throw an error as easy as before.
array_splice:
Removes the elements designated by $offset and $length from the $input array, and replaces them with the elements of the $replacement array, if supplied.
array_values:
Returns all the values from the $input array and indexes numerically the array.
