Example

Try out following 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 />");

?> 

This 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 )
