How would I create a switch statement equivalent to the following?

PHP Code:

<?php
if (!$_GET['value']) {
$variable = 'something'; }

else {
$variable = 'somethingElse'; }
?>

Thanks.

Don't use a case statement. Case can only operate on an instantiated variable.
Use the if shorthand rather

PHP Code:

$variable=(isset($_GET['value'])?'something':'nothing'; 


Explaination:
$variable=({test returning true or false}?{value if true}:{value if false};

Cool. The code I was using was quite different to the one in my example so I ending up solving it like this:

PHP Code:

    if ($_GET['contactStatus'])
        {
            $contactStatus = $_GET['contactStatus'];
            switch ($contactStatus)
                {
                    case '0':
                    displayDefault ();
                    break;
                    
                    case '1':
                    echo "Some of your information was invalid. Please ensure that You have filled valid information into each of the input fields.";
                    break;
                    
                    case '2':
                    echo "Your message has been sent successfully. We'll get back to you as soon as possible.";
                    break;
                    
                    case '3':
                    echo "There was an error processing your message. Please try again or use one of our alternate contact methods.";
                    break;
                }
            } 


Thanks!
