Syntax:
======
array array_slice ( array array, int offset [, int length])
Description:
=========
array_slice() returns the sequence of elements from the array array as specified by the offset and length parameters.
If offset is positive, the sequence will start at that offset in the array. If offset is negative, the sequence will start that far from the end of
the array.
If length is given and is positive, then the sequence will have that many elements in it. If length is given and is negative then the sequence
will stop that many elements from the end of the array. If it is omitted, then the sequence will have everything from offset up until the end of the
array.
Example:
=======
$input = array (”a”, “b”, “c”, “d”, “e”);
$output = array_slice ($input, 3);
it extracts from the 3rd element of the array. It returns “d”, and “e”
$output = array_slice ($input, 2, -1);
it extracts from the 2nd element upto (last-1) element of the array. It returns “c”, and “d”
$output = array_slice ($input, -2, 1);
it extracts one elements from the (last-2) position of the array. It returns “d”
$output = array_slice ($input, -4, 2);
it extracts two elements from the (last-4) position of the array. It returns “b”, and “c”.
