while loop inside array

[Annaccond]

I have a class to change urls from Opencart. There's array of urls and their new values. My problem is I'd like to get those urls and values from mySQL database.

Original array is something as this:

var $pages = array('contact' => 'common/home', 'search' => 'product/search', ...); 

I tried to do it this way:

while ($row = mysql_fetch_array($result)) {
$pages[] = array($row['route_seo_url'] => $row['route_old_url']);
} 

and inside class:

var $pages = array(); 

but it doesn't work.

This is whole original code:

class ControllerCommonRoute extends Controller {

var $pages = array('contact' => 'common/home', 'search' => 'product/search', ...);

    public function check() {

        $uri = substr(str_replace(strrchr($this->request->server['REQUEST_URI'], '?'), '', $this->request->server['REQUEST_URI']),1 );
        $uri = (substr($uri, -1)=='/')? $uri = substr($uri, 0, strrpos($uri, '/')) : $uri;

        if((!isset($this->request->get['route'])) AND (trim($uri) <> '')){
            if(array_key_exists($uri, $this->pages)){
              $this->request->get['route'] = $this->pages[$uri];
              return $this->forward($this->pages[$uri]);
            }
        }


    }
} 

Any suggestions will be appreciated.

setting an array value

$pages[] 

creating an array variable

$pages 

$pages =array($row['route_seo_url'],$row['route_old_url']);
$pages[0] // route_seo_url
$pages[1] // route_old_url 

$pages[] =array($row['route_seo_url'],$row['route_old_url']);
$pages[0][0] // route_seo_url
$pages[0][1] // route_old_url
