How display on OSM on my website, markers taken from MySQL database?

Hi everybody,

on my website, I would like to display an OSM where the users can add markers via PHP form. The data are taken from MySQL database and displayed onto an HTML page. No need to edit the original maps. Step 1: User adds a location, giving an address, zip code, city, Step 2: I get the geo-coordinates from the address, Step 3: the map displays the information taken from MySQL database.

Is it possible with OSM? If so, how?

Thanks in advance,

Prisco
