How can elseif statements improve the readability and functionality of PHP code?

Using elseif statements in PHP can improve the readability and functionality of code by allowing for multiple conditional branches to be evaluated in a clear and organized manner. This can help reduce nested if-else structures and make the code easier to understand and maintain. 

$score = 85;

if ($score >= 90) {
    echo "A";
} elseif ($score >= 80) {
    echo "B";
} elseif ($score >= 70) {
    echo "C";
} elseif ($score >= 60) {
    echo "D";
} else {
    echo "F";
}
