What are the advantages of using if..elseif statements over switch-case statements in PHP?

Using if..elseif statements can be advantageous over switch-case statements in PHP because if..elseif statements allow for more complex conditions to be evaluated, making it easier to handle multiple conditions within a single block of code. Additionally, if..elseif statements offer more flexibility in terms of the types of conditions that can be checked, as they can include logical operators and functions. Overall, if..elseif statements can result in more readable and maintainable code compared to switch-case statements.

$grade = 'B';

if ($grade == 'A') {
    echo 'Excellent';
} elseif ($grade == 'B') {
    echo 'Good';
} elseif ($grade == 'C') {
    echo 'Fair';
} else {
    echo 'Needs Improvement';
