I have a Google map embedded on my site that dynamically generates by taking the address and zip code from a SQL database. I am not bothering w/ coordinates, and I am happy with the results so far. The code I use is listed below (with a made-up address and zip, normally would get value from the database), and works just fine for one address.
However, there are some pages that will result in multiple addresses, and I'd like to generate multiple markers on the map to represent those addresses. I am using PHP. Any ideas?
$address = "111 South Main Street";
$zip = 55555;
