PHP Basic Algorithm: Exercise-6 with Solution

Write a PHP program to remove the character in a given position of a given string. The given position will be in the range 0..string length -1 inclusive.

Sample Solution:

PHP Code :

<?php
// Define a function named "test" that takes two parameters, $s and $n
function test($s, $n) 
{
    // Use the substr function to concatenate the substring of $s from index 0 to $n-1
    // with the substring of $s from index $n+1 to the end of the string
    return substr($s, 0, $n) . substr($s, $n + 1, strlen($s) - $n);
}

// Call the test function with arguments "Python" and 1, then echo the result
echo test("Python", 1) . "\n";

// Call the test function with arguments "Python" and 0, then echo the result
echo test("Python", 0) . "\n";

// Call the test function with arguments "Python" and 4, then echo the result
echo test("Python", 4) . "\n";
