What are some best practices for handling conditional statements in PHP to avoid confusion?

One best practice for handling conditional statements in PHP to avoid confusion is to use proper indentation and formatting to make the code more readable. Additionally, it's important to use clear and descriptive variable names to make the logic of the conditionals easier to understand. Lastly, avoid nesting too many levels of if-else statements to prevent code complexity. 

// Example of using proper indentation and clear variable names
$age = 25;

if ($age >= 18) {
    echo "You are an adult.";
} else {
    echo "You are not an adult.";
}
