Open google map taking the address from PHP variable

Question

I have an address stored in a php variable (say $add). I am trying to create a link in my Web App, which when clicked will open the Google Maps App in the iPhone with the $add marked. I don't want to embed the map in the web app.

Can anyone give a few pointers how to go about it?

Answer 1

Just link to http://maps.google.com/maps?q=<?=$add?> this should open the maps app on iPhone by default (and android incidentally)

Answer 2

You can send the data over url parameters:
