Can I use the same case value multiple times in a switch

Question

Can I write a switch statement like this?

   switch ($mood) {

    case hungry : 
    case sad : 
    echo 'Eat a chocolate';


    case sad : 
    echo 'Call Up your friend';

    }

Is this a good practice?

EDIT : Removed the break statement, based on the comment.

It is technically possible to define multiple cases with the same value, but only the first case will get executed. So it's pretty much useless.

From the switch() documentation:

PHP continues to execute the statements until the end of the switch block, or the first time it sees a break statement.

Since the first case has a break in it, further cases won't be executed and the code will exit the switch() block.

Consider the following piece of code:

$var = 'sad';

switch ($var) {
    case 'sad':
        echo 'First';
        break;
    case 'sad':
        echo 'Second';
        break;
}

This will output First.

If you want to execute multiple statements if a condition is TRUE, then add them under the same case, like so:

switch ($var) {
    case 'sad':
        echo 'First';
        echo 'Second';
        break;
}
