PHP switch case more than one value in the case

I have a variable that holds the values 'Weekly', 'Monthly', 'Quarterly', and 'Annual', and I have another variable that holds the values from 1 to 10.

switch ($var2) {
    case 1:
        $var3 = 'Weekly';
        break;
    case 2:
        $var3 = 'Weekly';
        break;
    case 3:
        $var3 = 'Monthly';
        break;
    case 4:
        $var3 = 'Quarterly';
        break;
    case 5:
        $var3 = 'Quarterly';
        break;
    // etc.
}

It isn't beautiful, because my code has a lot of duplicates. What I want:

switch ($var2) {
    case 1, 2:
        $var3 = 'Weekly';
        break;
    case 3:
        $var3 = 'Monthly';
        break;
    case 4, 5:
        $var3 = 'Quarterly';
        break;
}

How can I do it in PHP?

If You're reading this and the year is 2021 and beyond, You're also using PHP > 8.0, you can now use the new match expression for this.

this could be

$var3 = match($var2){
    1, 2    => 'Weekly',
    3       => 'Monthly',
    4, 5    => 'Quarterly',
    default => 'Annually',
};

Please note that match does identity checks, this is the same as === compared to switch equality check which is ==.

You could use array to store you match groups; like:

    <?php
    $names = array('Ian', 'Jack', 'Fred', 'Ismail');
    $name = 'Vladimir';
    switch ($name) {
    case (in_array($name, $names)):
            echo '<p> Welcome ' . $name . '</p>';
            break;
        default:
            echo '<p>' . $name . ' is a stranger to me?</p>';
    }
?>

Switch is also very handy for A/B testing. Here is the code for randomly testing four different versions of something:

$abctest = mt_rand(1, 1000);
switch ($abctest) {
    case ($abctest < 250):
        echo "A code here";
        break;
    case ($abctest < 500):
        echo "B code here";
        break;
    case ($abctest < 750):
        echo "C code here";
        break;
    default:
        echo "D code here";
        break;

The simplest and probably the best way performance-wise would be:

switch ($var2) {
    case 1:
    case 2:
       $var3 = 'Weekly';
       break;
    case 3:
       $var3 = 'Monthly';
       break;
    case 4:
    case 5:
       $var3 = 'Quarterly';
       break;
}

Also, possible for more complex situations:

switch ($var2) {
    case ($var2 == 1 || $var2 == 2):
        $var3 = 'Weekly';
        break;
    case 3:
        $var3 = 'Monthly';
        break;
    case ($var2 == 4 || $var2 == 5):
        $var3 = 'Quarterly';
        break;
}

In this scenario, $var2 must be set and can not be null or 0

switch ($var2) {
       case 1 :
       case 2 :
          $var3 = 'Weekly';
          break;
       case 3 :
          $var3 = 'Monthly';
          break;
       case 4 :
       case 5 :
          $var3 = 'Quarterly';
          break;
}

Everything after the first matching case will be executed until a break statement is found. So it just falls through to the next case, which allows you to "group" cases.
