In Swift you can group multiple conditions with a comma `,` and in Rust with a
pipe `|`. Here’s how that could look in PHP:
```php
match ($x) {
1, 2: ‘One or two’;
}
```
The only thing you cannot do is this:
```php
switch ($x) {
case 1:
echo “One\n”;
case 2:
echo “Two\n”;
break;
}
```
Meaning you cannot “bleed through” the first case into the second, executing
both in case of `$x` being `1`. This is acceptable IMO because this looks like
a bug even if it’s intended.

Because that’s usually the perfect use case for a switch statement.
