I have written a function to print database to an array like this

Array(
    ID=>1,
    PARENTID =>1,
    TITLE => LIPSUM,
    TEXT =>LIPSUM
    )

My function is:

function dbToArray($db)
                        {
                          $allArrays =array();
                          $query = mysql_query("SELECT * FROM $db");
                          $dbRow = mysql_fetch_array($query);
                            for ($i=0; $i<count($dbRow)  ; $i++)
                                {
                                   $allArrays[$i] =  $dbRow; 
                                }
                            $txt .='<pre>';
                            $txt .= print_r($allArrays);
                            $txt .= '</pre>';
                            return $txt;
                        }

Anything wrong in my function. Any help is appreciated about my problem. Thanks in advance
