What are the key differences between using if/elseif/else statements and switch/case statements in PHP for handling multiple conditions?

When handling multiple conditions in PHP, if/elseif/else statements are typically used for more complex conditions where each condition may be different. On the other hand, switch/case statements are ideal for scenarios where a single variable is being compared against multiple values. Switch/case statements can make the code more readable and maintainable in such cases. 

// Example using if/elseif/else statements
$grade = 'B';

if ($grade == 'A') {
    echo 'Excellent';
} elseif ($grade == 'B') {
    echo 'Good';
} elseif ($grade == 'C') {
    echo 'Average';
} else {
    echo 'Below Average';
}

// Example using switch/case statements
$grade = 'B';

switch ($grade) {
    case 'A':
        echo 'Excellent';
        break;
    case 'B':
        echo 'Good';
        break;
    case 'C':
        echo 'Average';
        break;
    default:
        echo 'Below Average';
}
