How can you ensure that only one switch statement is executed based on the URL parameters in PHP?

To ensure that only one switch statement is executed based on the URL parameters in PHP, you can use a combination of conditional statements and a flag variable to track whether a switch statement has already been executed. By setting the flag variable after executing a switch statement, you can prevent subsequent switch statements from being executed. 

$flag = false;

if(isset($_GET['param1']) && !$flag) {
    switch($_GET['param1']) {
        case 'value1':
            // code block for param1 value1
            $flag = true;
            break;
        case 'value2':
            // code block for param1 value2
            $flag = true;
            break;
        default:
            // default code block
    }
}

if(isset($_GET['param2']) && !$flag) {
    switch($_GET['param2']) {
        case 'value3':
            // code block for param2 value3
            $flag = true;
            break;
        case 'value4':
            // code block for param2 value4
            $flag = true;
            break;
        default:
            // default code block
    }
}
