What is the difference between array_slice() and array_splice()?

The difference between array_slice() and array_splice()

array_splice() is used to remove some elements from an array and replace with specified elements.
Below are some code examples:

<?php

$input = array("red", "green", "blue", "yellow");

array_splice($input, 2);

// $input is now array("red", "green")

$input = array("red", "green", "blue", "yellow");

array_splice($input, 1, -1);

// $input is now array("red", "yellow")

$input = array("red", "green", "blue", "yellow");

array_splice($input, 1, count($input), "orange");

// $input is now array("red", "orange")

$input = array("red", "green", "blue", "yellow");

array_splice($input, -1, 1, array("black", "maroon"));

// $input is now array("red", "green",

// "blue", "black", "maroon")

$input = array("red", "green", "blue", "yellow");

array_splice($input, 3, 0, "purple");

// $input is now array("red", "green",

// "blue", "purple", "yellow");

?>

 array_slice() is used to extract a slice of the array. Below are some example codes:

<?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

)
