PHP array_splice() Function



Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial, we will be studying about the PHP Function array_splice().

The PHP array_splice() function removes the elements selected by offset and length from the input array, and replaces them with the elements of the replacement array, if it is supplied. It returns an array containing the extracted elements.

Syntax

Following below is the syntax to use this function -

array_splice ( $input, $offset [,$length [,$replacement]] );


Parameter Details

Sr.NoParameter & Description
1

input(Required)

It specifies an array

2

offset

It specifies where the function will start removing elements. 0 = the first element.

3

length(Optional)

It specifies how many elements will be removed, and also length of the returned array.

4

replacement(Optional)

It specifies an array with the elements that will be inserted to the original array.


Return Value

This built-in function returns the last value of the array, shortening the array by one element.

Example

Try out the below example -

<?php
   $input = array("red", "black", "pink", "white");
   array_splice($input, 2);
   print_r($input);
   print_r("<br />");

   $input = array("red", "black", "pink", "white");
   array_splice($input, 1, -1);
   print_r($input);
   print_r("<br />");

   $input = array("red", "black", "pink", "white");
   array_splice($input, 1, count($input), "orange");
   print_r($input);
   print_r("<br />");

   $input = array("red", "black", "pink", "white");
   array_splice($input, -1, 1, array("black", "maroon"));
   print_r($input);
   print_r("<br />");

   $input = array("red", "black", "pink", "white");
   array_splice($input, 3, 0, "purple");
   print_r($input);
   print_r("<br />");

?> 

Output

When the above code is executed, it will produce the following result -

Array ( [0]=>red [1] =>black )
Array ( [0]=>red [1] =>white )
Array ( [0]=>red [1] =>orange )
Array ( [0]=>red [1] =>black [2]=>pink [3]=>black [4]=>maroon )
Array ( [0]=>red [1] =>black [2]=>pink [3]=>purple [4]=>white )
