Answers for "php array_slice and get slicing"

php array slice

// array_slice($array, $offset, $length)

$array = array(1,2,3,4,5,6);

// positive $offset: an offset from the begining of array  
print_r(array_slice($array, 2)); // [3,4,5,6]

// negative $offset: an offset from the end of array
print_r(array_slice($array, -2)); // [5,6]

// positive $length: the slicing will stop $length elements
// from offset
print_r(array_slice($array, 2, 3)); // [3,4,5]

// negative $length: the slicing will stop $length elements
// from the end of array
print_r(array_slice($array, 2, -3)); // [3]

php array subset by slicing

<?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));
?>
