| * |
| * Example of use: |
| * <code> |
| * // register an URL under the alias 'map' |
| * ezcUrlCreator::registerUrl( 'map', '/images/geo/%s?xsize=%d&ysize=%d&zoom=%d' ); |
| * |
| * // retrieve the stored URL under the alias 'map' formatted with parameters |
| * $url = ezcUrlCreator::getUrl( 'map', 'map_norway.gif', 450, 450, 4 ); |
| * // will be: "/images/geo/map_norway.gif?xsize=450&ysize=450&zoom=4" |
| * |
| * // retrieve the stored URL under the alias 'map' formatted with other parameters |
| * $url = ezcUrlCreator::getUrl( 'map', 'map_sweden.gif', 450, 450, 4 ); |
