php - Google Maps V3 API for Codeigniter [Adding Numbered Markers + other questions] -

i have several questions regarding google map v3 api , library codeigniter wraps php class google maps api.

1. how can have marker show a,b,c… or 1,2,3…? (most important)

2. how prevent white bubble box opening when click on marker?

3. after adding marker using addmarkerbyaddress() inside controller, there function can call within controller remove marker? because after adding directions it, marker addmarkerbyaddress() overlaps start/end marker in case need remove initial marker.

4. i cannot seem have map display without calling addmarkerbyaddress(), right?

this has been bothering me days hope can me out!!

for showing custom markers use this:

var latlon2 = new google.maps.latlng(44.959944, 26.0186218); marker2 = new google.maps.marker({               position: latlon2,               map: map,               icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=a|ff0000|000000'              });
