How can a switch statement be utilized in PHP to streamline the inclusion of different files based on a variable?

When including different files based on a variable in PHP, a switch statement can be used to streamline the process. By evaluating the variable and using a switch statement to determine which file to include, the code becomes more organized and easier to maintain.

// Example of using a switch statement to include different files based on a variable
switch ($variable) {
    case 'file1':
        include 'file1.php';
        break;
    case 'file2':
        include 'file2.php';
        break;
    case 'file3':
        include 'file3.php';
        break;
    default:
        include 'default.php';
}
