PHP Basic Algorithm: Exercise-68 with Solution

Write a PHP program to move the last two characters to the start of a given string of length at least two.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that rearranges the last two characters of a string with the rest of the string
function test($s1)
{ 
    // Use substr to extract substrings and rearrange them
    return substr($s1, strlen($s1) - 2, 2) . substr($s1, 0, strlen($s1) - 2);
}

// Test the 'test' function with different strings and display the results
echo test("Hello")."\n";
echo test("JS")."\n";
?>
