How can the use of switch case statements in PHP impact performance compared to other methods like if-else statements?

Using switch case statements in PHP can be more efficient than using multiple if-else statements when dealing with a large number of conditions. Switch case statements allow for direct comparison of a variable against multiple values, which can result in faster execution compared to nested if-else statements. However, the performance difference between switch case and if-else statements may vary depending on the specific use case and the number of conditions being evaluated. 

// Example of using switch case statements for better performance
$fruit = "apple";

switch ($fruit) {
    case "apple":
        echo "It's an apple!";
        break;
    case "banana":
        echo "It's a banana!";
        break;
    case "orange":
        echo "It's an orange!";
        break;
    default:
        echo "Unknown fruit!";
}
