I am trying to access the $db variable in my custom function but it isn't working not sure why.  It has something to do with scope but I would like the function to access the $db variable.

Here is my code below

/*Connect to the database.*/
$db=new db("mysql:host=localhost;dbname=mydb", "mydb", "mydb123");


/*Get database value*/
function retVal($table,$field,$val,$returnVal)
{
    $dataReturn = $db->select($table, $field."= '".$val."'");

    /*Loop THru array and load it with values */
    foreach ($dataReturn[0] as $key=>$value) {
        $dataArray[$key]=$value;
    }

    return $dataArray[$returnVal];

}
/*End function return value */
