What are best practices for conditional statements in PHP to ensure correct output?

When working with conditional statements in PHP, it is important to ensure that the conditions are properly structured to produce the desired output. To ensure correct output, use logical operators such as && (AND), || (OR), and ! (NOT) to combine multiple conditions. Additionally, make sure to use parentheses to clarify the order of operations when combining multiple conditions. 

// Example of using logical operators and parentheses in conditional statements
$age = 25;
$is_student = true;

if ($age >= 18 && $is_student) {
    echo "You are a student over 18 years old.";
} else {
    echo "You are either not a student or under 18 years old.";
}
