How can the logic in PHP code be optimized to handle scenarios where the expected output may not align with traditional mathematical comparisons?

When dealing with scenarios where the expected output may not align with traditional mathematical comparisons in PHP, it is important to use logical operators and conditional statements to handle these cases effectively. By using logical operators such as "&&" (AND), "||" (OR), and "!" (NOT), along with conditional statements like if-else or switch-case, you can optimize the logic in your PHP code to cater to these specific scenarios.

// Example PHP code snippet demonstrating the use of logical operators and conditional statements to handle non-traditional comparisons

$number = 15;

// Checking if the number is a multiple of both 3 and 5
if ($number % 3 == 0 && $number % 5 == 0) {
    echo "The number is a multiple of both 3 and 5.";
} 
// Checking if the number is a multiple of either 3 or 5
elseif ($number % 3 == 0 || $number % 5 == 0) {
    echo "The number is a multiple of either 3 or 5.";
} 
// If none of the above conditions are met
else {
    echo "The number is not a multiple of 3 or 5.";
}
