Write a PHP program to create a new array length 3 from a given array (length atleast 3) using the elements from the middle of the array.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
 { 
    // Calculate the index of the middle element in the array
    $middleIndex = sizeof($numbers) / 2;
    
    // Return a new array containing the three elements around the middle of the input array
    return [$numbers[$middleIndex - 1], $numbers[$middleIndex], $numbers[$middleIndex + 1]];
 }   

// Call the 'test' function with an array [1, 5, 7, 9, 11, 13] and store the result in $result
$result = test([1, 5, 7, 9, 11, 13]);

// Print the new array containing the three elements around the middle using 'implode' and 'echo'
echo "New array: " . implode(',', $result);
?>

Sample Output:

New array: 7,9,11
