Last update on December 20 2024 10:20:18 (UTC/GMT +8 hours)

Write a PHP program that accept two integers and return true if either one is 5 or their sum or difference is 5.

Sample Solution:

PHP Code :

<?php
// Define a function that checks conditions related to the numbers
function test($x, $y)
{
    // Check if $x is 5 or $y is 5 or the sum of $x and $y is 5
    // or the absolute difference between $x and $y is 5
    return $x == 5 || $y == 5 || $x + $y == 5 || abs($x - $y) == 5;
}

// Test the function with different pairs of numbers
var_dump(test(5, 4));
var_dump(test(4, 3));
var_dump(test(1, 4));
?>

Explanation:

• Function Definition:
• The test function takes two numbers, $x and $y, as parameters and checks several conditions.
• Conditions Checked:
• It checks if:
• $x is equal to 5.
• $y is equal to 5.
• The sum of $x and $y is 5.
• The absolute difference between $x and $y is 5.
• If any of these conditions are true, the function returns true; otherwise, it returns false.

Output:

bool(true)
bool(false)
bool(true)
