[GIS] Get coordinates from address

addresscoordinatesgeocodingjavascriptPHP

I am writing a application which allow users to save a address into database (db) and in the next step it shows all addresses on a map. But in the saving step I need automatically calculate a GPS coordinates and save them into db too. But I don't know how calculate them because I don't want to show map in saving step so I can't use a Google Maps API.

Note: the Geocoding API may only be used in conjunction with a Google map; 
geocoding results without displaying them on a map is prohibited.

Is there a similar service without the restriction?

ESRI's geoservice's are also simular to google's.

For example fetching a json result for Antwerp: http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/find?text=antwerp&f=pjson

And they also support multiple languages.

[GIS] Geocoding addresses from MySQL and adding them like markers to Google map

The Official Google Maps API v3 has a good tutorial on this.

Note: Some tutorials may suggest actually writing your map page as a PHP file and outputting JavaScript for each marker you want to create, but that technique can be problematic. By using an XML file as an intermediary between your database and your Google Map, it makes for a faster initial page load, a more flexible map application, and easier debugging. You can independently verify the XML output from the database and the JavaScript parsing of the XML. And at any point, you could even decide to eliminate your database entirely and just run the map based on static XML files.

Leaflet Geocoding – Address Searching using Leaflet for Improved Mapping

I tried too and failed. Here is an option that uses OSM and has other options. https://github.com/perliedman/leaflet-control-geocoder

and a HTML page that works using it.

<!DOCTYPE html>
<html>
<head><title>Leaflet</title>
 <link rel="stylesheet" href="https://unpkg.com/leaflet@1.3.1/dist/leaflet.css" />
<script src="https://unpkg.com/leaflet@1.3.1/dist/leaflet.js"></script>

<link rel="stylesheet" href="https://unpkg.com/leaflet-control-geocoder/dist/Control.Geocoder.css" />
<script src="https://unpkg.com/leaflet-control-geocoder/dist/Control.Geocoder.js"></script>     
</head>
<body>
    <style> #map {width: 100%;height: 100%; }   </style>

<div id="map"></div>

<script>
//Example from https://github.com/perliedman/leaflet-control-geocoder  
    var map = L.map('map').setView([42.697765, -73.108005], 3);  

    var osm=new L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png').addTo(map);

    L.Control.geocoder().addTo(map);

</script>
