Write a PHP program to create a new array swapping the first and last elements of a given array of integers and length will be least 1.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
 { 
    // Store the value of the first element in a variable named $first
    $first = $numbers[0];
    
    // Swap the value of the first element with the value of the last element in the array
    $numbers[0] = $numbers[sizeof($numbers) - 1];
    
    // Set the value of the last element to the stored value of the first element
    $numbers[sizeof($numbers) - 1] = $first;
    
    // Return the modified array after swapping the first and last elements
    return $numbers;
 }   

// 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 after swapping the first and last elements using 'implode' and 'echo'
echo "New array, after swapping first and last elements: " . implode(',', $result);
?>

Sample Output:

New array, after swapping first and last elements: 13,5,7,9,11,1
