2. Array_splice() Method

Unset() Method

The unset() method is a built-in function in PHP that is used to remove or unset a single element from the array. Check out the syntax.

Example

<?php

  $arr = array("john","mark", "noah", "peter");
  unset($arr[2]);
  print_r($arr);

?>

Output

Array (
[0] => jhon
[1] => mark
[3] => peter
)

Array_splice() Method

The array_splice function is used when you want to delete or remove or replace an element from the array.

Example

<?php

 $top = ["a"=> "AI", "b"=>"Programming", "c"=>"Python", 
 "d"=> "PHP"];
 array_splice($top, 2, 1);
 echo "<pre>";
 print_r($top);
 echo "</pre>";

?>

Output

Array
(
[a] => AI
[b] => programming
[d] => php
)
