What are common errors to avoid when using switch statements in PHP for conditional logic?

One common error to avoid when using switch statements in PHP for conditional logic is forgetting to include a "break" statement at the end of each case. This can lead to unintended fall-through behavior where multiple cases are executed. To solve this issue, always remember to include a "break" statement at the end of each case to ensure that only the intended case is executed. 

// Incorrect switch statement without break statements
$fruit = "apple";

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

```php
// Correct switch statement with break statements
$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 "It's a fruit.";
}
