PHP Exercises: Concat two given string of length atleast 1, after removing their first character

PHP Basic Algorithm: Exercise-66 with Solution

Write a PHP program to concat two given string of length atleast 1, after removing their first character.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that concatenates substrings excluding the first character
function test($s1, $s2)
{ 
    // Use substr to extract substrings excluding the first character and concatenate them
    return substr($s1, 1, strlen($s1) - 1) . substr($s2, 1, strlen($s2) - 1);
}

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

Explanation:

• Function Definition:
• The function test is defined to take two string parameters, $s1 and $s2.
• Substring Extraction:
• Inside the function, substr is used to extract substrings from both $s1 and $s2, excluding their first characters:
• substr($s1, 1, strlen($s1) - 1) extracts all characters from $s1 starting from the second character.
• substr($s2, 1, strlen($s2) - 1) does the same for $s2.
• Concatenation:
• The function returns the concatenated result of these substrings from $s1 and $s2.
