                                  array_slice

   (PHP 4 )
   array_slice -- Extract a slice of the array

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.

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