PHP Basic Algorithm: Exercise-69 with Solution

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that extracts the middle portion of a string, excluding the first and last characters
function test($s1)
{ 
    // Check if the string has less than 2 characters and return an empty string if true
    return strlen($s1) < 2 ? "" : substr($s1, 1, strlen($s1) - 2);
}

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