array_slice - Extract a slice of the array

SYNOPSIS

       array array_slice NULL (array  $array, int  $offset, [int  $length], [bool  $preserve_keys = false])

DESCRIPTION

       array_slice(3) returns the sequence of elements from the array $array as specified by the $offset and $length parameters.

PARAMETERS

	      o $array
		- The input array.

	      o $offset
		-  If  $offset	is  non-negative,  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.

	      o $length
		- If $length is given and is positive, then the sequence will have up to that many elements in it. If the array  is  shorter  than
		the  $length,  then  only the available array elements will be present. 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.

	      o $preserve_keys
		-  Note  that array_slice(3) will reorder and reset the numeric array indices by default. You can change this behaviour by setting
		$preserve_keys to TRUE.

RETURN VALUES

	Returns the slice.

EXAMPLES

       Example #1

	      array_slice(3) 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 "d"
	      $output = array_slice($input, 0, 3);   // returns "a", "b", and "c"

	      // note the differences in the array keys
	      print_r(array_slice($input, 2, -1));
	      print_r(array_slice($input, 2, -1, true));
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => c
		  [1] => d
	      )
	      Array
	      (
		  [2] => c
		  [3] => d
	      )
