How can PHP developers optimize their code to handle multiple conditions and improve readability, as shown in the example code?

PHP developers can optimize their code by using switch statements instead of multiple if-else conditions when dealing with a large number of conditions. Switch statements can improve readability and make the code more maintainable. By organizing conditions into cases, developers can easily see the different scenarios and handle them efficiently.

// Example of using switch statement to handle multiple conditions
$condition = 'case2';

switch ($condition) {
    case 'case1':
        // Code block for case1
        break;
    case 'case2':
        // Code block for case2
        break;
    case 'case3':
        // Code block for case3
        break;
    default:
        // Default code block
        break;
}
