What is the purpose of using a switch statement in PHP for including different files based on a variable?

When you have a variable that determines which file to include in your PHP script, using a switch statement can provide a cleaner and more organized way to handle multiple cases. Instead of using multiple if-else statements, a switch statement can efficiently check the value of the variable and include the corresponding file based on the case.

// Example of using a switch statement to include different files based on a variable
$includeFile = "file1.php";

switch ($includeFile) {
    case "file1.php":
        include "file1.php";
        break;
    case "file2.php":
        include "file2.php";
        break;
    case "file3.php":
        include "file3.php";
        break;
    default:
        echo "Invalid file specified.";
}
