Is it recommended to perform arithmetic operations within if statements in PHP, or are there alternative approaches for better code readability and efficiency?

Performing arithmetic operations within if statements can make the code harder to read and maintain. It is recommended to perform the arithmetic operations separately and then use the result in the if statement for better code readability. This approach also helps in improving code efficiency as the arithmetic operations are not repeated unnecessarily within the if statement. 

// Perform arithmetic operations separately
$num1 = 10;
$num2 = 20;
$result = $num1 + $num2;

// Use the result in the if statement
if ($result > 20) {
    echo "The result is greater than 20.";
}
