In what situations would it be beneficial to switch from using if-elseif statements to a switch statement in PHP?

Switching from using if-elseif statements to a switch statement in PHP can be beneficial when you have multiple conditions to check against a single variable. Switch statements can make the code more readable and easier to maintain, especially when there are many cases to consider. Additionally, switch statements can be more efficient in terms of performance compared to long chains of if-elseif statements. 

// Using switch statement instead of if-elseif
$var = 'b';

switch ($var) {
    case 'a':
        echo "Variable is a";
        break;
    case 'b':
        echo "Variable is b";
        break;
    case 'c':
        echo "Variable is c";
        break;
    default:
        echo "Variable is not a, b, or c";
}
