1. Write a PHP script that inserts a new item in an array at any position. (hint : use array_splice())

 <?php

$arr=array(10,20,30,40,50);

echo "Before inserting elements in array,the array is : ";

print_r($arr);

$new=array(15,25);

$insert=array_splice($arr,3,0,$new);

echo "<br><br>After inserting elements in array,the array is : ";

print_r($arr);

/*OUTPUT-

Before inserting elements in array,the array is :

Array ( [0] => 10 [1] => 20 [2] => 30 [3] => 40 [4] => 50 )

After inserting elements in array,the array is :

Array ( [0] => 10 [1] => 20 [2] => 30 [3] => 15 [4] => 25 [5] => 40 [6] => 50 ) */

?>
