PHP Exercises: Create a new string without the first and last character of a given string of length atleast two

PHP Basic Algorithm: Exercise-64 with Solution

Write a PHP program to create a new string without the first and last character of a given string of length atleast two.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that manipulates the substring of s1
function test($s1)
{
    // Use substr to exclude the first character, then another substr to exclude the last two characters
    return substr(substr($s1, 1, strlen($s1) - 1), 0, strlen($s1) - 2);
}

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

Explanation:

• Function Definition:
• The function test takes one parameter, $s1, which is a string.
• Manipulate Substring:
• The function uses substr twice to exclude certain characters:
• substr($s1, 1, strlen($s1) - 1): Removes the first character from $s1.
• Another substr call then extracts a substring from the resulting string, stopping before the last two characters.
• Return:
• The function returns the modified substring, excluding the first and last two characters of the original $s1.

Output:
