How can proper order of operations be ensured in PHP mathematical calculations?

To ensure the proper order of operations in PHP mathematical calculations, you can use parentheses to explicitly define the order in which operations should be performed. By enclosing expressions in parentheses, you can ensure that calculations are carried out according to the correct precedence rules.

// Example of using parentheses to ensure proper order of operations
$result = (5 + 3) * 2; // This will first add 5 and 3, then multiply the result by 2
echo $result; // Output: 16
