This calculation is equivalent to `strtr($class, '.', '·')`.

For this given declaration:
```php
<?php
  $package= 'com.example';

  class com·example·ClassName extends Object {
?>
```

...te result is `$name= 'com·example'.'·'.'ClassName'` => 'com·example·ClassName'. There would only be a difference if the package was not equal to the string before the last dot in the classname, which would raise other errors.
