How can PHP developers avoid issues with type-weak comparisons in switch/case statements?

Type-weak comparisons in switch/case statements can lead to unexpected behavior due to PHP's loose type-checking. To avoid issues, developers should use strict type comparisons (===) instead of weak type comparisons (==) in switch/case statements. This ensures that both the value and type are compared, reducing the likelihood of bugs caused by type coercion. 

$fruit = "apple";

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