Some quick fixes. Even if you don't use inflector camelise

it should work. I learned a fact that PHP don't have any problem with caps or small.

Eg: 

```php
<?php
class Hello
{
    public function getHello()
    {
        return "Hello";
    }

    public function getWorld()
    {
        return "World!";
    }
}

$hello = new Hello();
echo $hello->getHello();

echo PHP_EOL . $hello->getworld();
```
