How can one ensure that multiple conditions are properly evaluated in PHP if elseif else statements?

When using if, elseif, else statements in PHP, it's important to ensure that each condition is properly evaluated in the correct order. To do this, make sure that each condition is mutually exclusive and that the conditions are evaluated in the correct order to avoid unexpected behavior. 

$score = 85;

if ($score >= 90) {
    echo "A";
} elseif ($score >= 80) {
    echo "B";
} elseif ($score >= 70) {
    echo "C";
} else {
    echo "D";
}
