### Filter

[](#filter)

All filters that implement the filter interface in this library must implement a `filter()` function that returns the filtered value, for example a filter to make a string lowercase might look as follows:

```
use \District5\Filter\FilterInterface;

class MyStringToLowerFilter implements FilterInterface
{
    public function filter($value)
    {
        if (extension_loaded('mbstring')) {
            return mb_strtolower($value);
        }

        return strtolower($value);
    }
}
```
