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

Using elseif statements in PHP can improve efficiency and readability by allowing for more specific conditions to be checked in a single block of code. This can reduce the need for nested if statements and make the code easier to follow. By using elseif, you can avoid unnecessary checks once a condition is met, leading to faster execution of the code. 

$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";
}
