Semi-colon after a case valid in a PHP switch statement?

Question

I'm debugging some code for a client and found the following syntax:

switch ($i) {
    case 0;
        echo "i equals 0";
        break;
    case 1;
        echo "i equals 1";
        break;
    case 2;
        echo "i equals 2";
        break;
}

The case statements end in semi-colons rather than colons. Turns out this does compile, but is it legit? I've never seen that syntax before.

From the documentation:

It's possible to use a semicolon instead of a colon after a case like:

switch($beer)
{
    case 'tuborg';
    case 'carlsberg';
    case 'heineken';
        echo 'Good choice';
    break;
    default;
        echo 'Please make a new selection...';
    break;
}
