I think you may be asking how to have a link that you click on that takes you to Google Maps, to a predefined location such as your location so they can then zoom - then why use PHP ? Why not just copy and paste the link like this - Statue of Liberty
Your explanation is not that detailed. But assuming you in fact want to display a location on Google Maps based on user input. For example they enter an address click ‘Locate’ button and the map is displayed. Then that is beyond my skill set but you could check out Geocoding which is the process of converting an address int latitude and longitude - which you could feed into a Google Maps url -I don’t know much more about this but you could check out - Geocoding
But you will have to get familiar with the API
