PHP array_splice() Function

PHP array_splice() Function

Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP array_splice() Function.

The built-in PHP array_splice() function is used to remove 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.


Following below is the syntax to use this function -

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

Parameter Details

Sr.NoParameter & Description


It specifies an array



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



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



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

Return Value

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


Try out the below example -

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

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

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

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

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



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 )
