How can one ensure that if statements in PHP provide the desired results?

To ensure that if statements in PHP provide the desired results, it is important to carefully construct the conditions being checked within the if statement. This includes using the correct comparison operators, ensuring the variables being compared are of the same type, and considering all possible scenarios that could affect the outcome of the if statement. 

$age = 25;

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