How can the proper usage of the "else if" statement in PHP impact the functionality of conditional logic in code?

Using the "else if" statement in PHP allows for multiple conditions to be checked sequentially, providing more flexibility and control over the flow of the program. By properly structuring "if-else if" statements, we can ensure that only one block of code is executed based on the conditions being met, improving the efficiency and readability of the code. 

$grade = 85;

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