Description
array
array_slice ( array array, int offset [, int length])
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.
Note that array_slice() will ignore array
keys, and will calculate offsets and lengths based on the
actual positions of elements within the array.

<?php
$input = array("a", "b", "c", "d", "e");
$output = array_slice($input, 2); $output = array_slice($input, 2, -1); $output = array_slice($input, -2, 1); $output = array_slice($input, 0, 3); ?>
