wstyd się przyznać ale zapomniałem jak się odwołuje do klasy

Mam taką klasę i chciałbym się do niej odwołać z innego pliku aby tylko pobrać tablicę z wynikami...
class LoadDate{ private $showLoadDate; public function loadDate(){ $query = ' SELECT ads.idAds, ads.firmName, ads.category, ads.voivodeship, ads.city, ads.postCode, ads.street, ads.text, ads.phone, ads.phone2, ads.webSite, ads.mail, ads.pricing, ads.priceDown, ads.priceUp, ads.map, ads.keywords, ads.active, city.idCity, city.city, category.idCategory, category.category, voivodeship.idVoivodeship, voivodeship.voivodeship FROM ads INNER JOIN city on ads.city = city.idCity INNER JOIN category on ads.category = category.idCategory INNER JOIN voivodeship on ads.voivodeship = voivodeship.idVoivodeship WHERE ads.active = 1 AND ads.idAds = "15" '; $this->so->doit($query); while($this->so->next_record()){ $this->backString = $this->config->generator($firmName,$file); 'firmName' => $this->so->f('firmName'), 'city' => $this->so->f('city'), 'category' => $this->so->f('category'), 'voivodeship' => $this->so->f('voivodeship'), 'postCode' => $this->so->f('postCode'), 'street' => $this->so->f('street'), 'mail' => $this->so->f('mail'), 'phone' => $this->so->f('phone'), 'phone2' => $this->so->f('phone2'), 'webSite' => $this->so->f('webSite'), 'priceDown' => $this->so->f('priceDown'), 'priceUp' => $this->so->f('priceUp'), 'pricing' => $this->so->f('pricing'), 'text' => $this->so->f('text') ); } return $this->showLoadDate; } }
pomoże ktoś ?
