Align equals

In that case I often write this like:
```php
    private function setDelimiters($delimiters)
    {
        list($otag, $ctag) = explode(' ', $delimiters);

        $this->otag    = $otag;
        $this->ctag    = $ctag;
        $this->otagLen = strlen($otag);
        $this->ctagLen = strlen($ctag);
    }
```

I separate them even, if I do not align `=`.
Grouping also help to understand things etter
