PHP Exercises: Create a new string from two given string one is shorter and another is longer

Last update on December 20 2024 10:26:35 (UTC/GMT +8 hours)

Write a PHP program to create a new string from two given string one is shorter and another is longer. The format of the new string will be long string + short string + long string.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that concatenates strings based on their lengths
function test($s1, $s2)
{ 
    // Use a ternary operator to determine the order of concatenation
    return strlen($s1) < strlen($s2) ? $s2 . $s1 . $s2 : $s1 . $s2 . $s1;
}

// 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 takes two string parameters, $s1 and $s2.

Concatenation Based on Length:

The function uses a ternary operator to concatenate the strings in different orders based on their lengths:

If the length of $s1 is less than $s2, it returns $s2 . $s1 . $s2 (places $s1 between two instances of $s2).
Otherwise, it returns $s1 . $s2 . $s1 (places $s2 between two instances of $s1).

Output:

HelloHiHello
PythonJSPython
