How can PHP developers optimize their code structure by using functions and improving readability, especially when dealing with complex switch-case constructs?

When dealing with complex switch-case constructs in PHP, developers can optimize their code structure and improve readability by encapsulating each case logic into separate functions. This approach not only makes the code easier to read and maintain but also promotes reusability and modularity. By breaking down the switch-case logic into smaller, focused functions, developers can enhance the overall structure of their code. 

function handleCaseA() {
    // Logic for case A
}

function handleCaseB() {
    // Logic for case B
}

function handleCaseC() {
    // Logic for case C
}

// Switch-case statement
switch ($variable) {
    case 'A':
        handleCaseA();
        break;
    case 'B':
        handleCaseB();
        break;
    case 'C':
        handleCaseC();
        break;
    default:
        // Default case logic
        break;
}
