PHP Exercises: Find the larger value from two positive integer values that is in the range 20..30 inclusive

PHP Basic Algorithm: Exercise-21 with Solution

Write a PHP program to find the larger value from two positive integer values that is in the range 20..30 inclusive, or return 0 if neither is in that range.

Sample Solution:

PHP Code :

<?php
// Define a function that compares two values based on certain conditions
function test($x, $y) 
{
    // Check if both $x and $y are within the range of 20 to 30
    if ($x >= 20 && $x <= 30 && $y >= 20 && $y <= 30) {
        // Compare $x and $y, return the greater value
        if ($x >= $y) {
            return $x;
        } else {
            return $y;
        }
    } elseif ($x >= 20 && $y <= 30) {
        // Check if only $x is within the range, return $x
        return $x;
    } elseif ($y >= 20 && $y <= 30) {
        // Check if only $y is within the range, return $y
        return $y;
    } else {
        // Return 0 if neither condition is met
        return 0;
    }
}

// Test the function with different sets of coordinates
echo test(78, 95)."\n";
echo test(20, 30)."\n";
echo test(21, 25)."\n";
echo test(28, 28)."\n";
?>

Sample Output:

0
30
25
28
