PHP: Breaks in default case switches?

php switch-statement case break

switch ($var) {
    case 0:
        // Do something...
        break;
    case 1:
        // Do something...
        break;
    default:
        // Do something...
        break;
}

I've seen some people use break at the end of the default case. Since the default case is the last case that's executed when triggered, is there any need to have a break there? I'm guessing it's just done out of common practice or is there another reason?

There's no reason its required so long as the default is at the end of the switch statement. Note that the default doesn't need to be the last case: http://codepad.viper-7.com/BISiiD

<?php
$var = 4;
switch($var)
{
    default:
        echo "default";
        break;
    case 4:
        echo "this will be executed";
        break;
}
