Just wandering, will it be possible for me to using the existing latitude and longitude data from the local database and search it in the google map to display the location on the google map?

Example: I have a database that saved all the latitude and longitude data. I wrote a system with php to retrieve the latitude and longitude data from the database then search it in the google map. Will it be possible?

Any idea where can I get the tutorial or example code about this case?

• php
• google-maps

EDIT::

You can use openstreet map. I think it's free. Check these links for openstreetmap:

Not sure what you are asking but yes you can use Long/Lat data to show a location. There are several ways to use google maps the most common is using the javascript api:

You can also use the static image method which is a bit more complicated:

If you don't have the Long/Lat data you can always use google maps to do geocoding to get the point:
