PHP Exercises: Check if a given string ends with "on"

PHP Basic Algorithm: Exercise-71 with Solution

Write a PHP program to check if a given string ends with "on".

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that extracts the last two characters from the input string
function test($s1)
{ 
   // Use substr to obtain the last two characters of the input string
   return substr($s1, strlen($s1)-2, 2);
}

// Test the 'test' function with different strings and display the results using var_dump
var_dump(test("Hello"));
var_dump(test("Python"));
var_dump(test("on"));
var_dump(test("o"));
?>

Sample Output:

string(2) "lo"
string(2) "on"
string(2) "on"
string(1) "o"
