    var myMap;
    var myLatlng = new google.maps.LatLng(52.518903284520796,-1.450427753967233);
    function initialize() {
        var mapOptions = {
            zoom: 13,
            center: myLatlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP  ,
            scrollwheel: false
        }
        myMap = new google.maps.Map(document.getElementById('map'), mapOptions);
        var marker = new google.maps.Marker({
            position: myLatlng,
            map: myMap,
            title: 'Name Of Business',
            icon: 'http://www.google.com/intl/en_us/mapfiles/ms/micons/red-dot.png'

    google.maps.event.addDomListener(window, 'load', initialize);
</script>

在这种情况下，您可以使用Geocoding service

function initMap() {

  //var address = '<?php echo $location ?>';
  var address = 'Kigali Rwanda';

  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 8
  });

  var geocoder = new google.maps.Geocoder();

  geocoder.geocode({
      'address': address
    },
    function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
        new google.maps.Marker({
          position: results[0].geometry.location,
          map: map
        });
        map.setCenter(results[0].geometry.location);
      }
    });
}

#map {
  height: 400px;
  width: 100%;
}

<h3>My Google Maps Demo</h3>
<div id="map"></div>
<!-- Replace the value of the key parameter with your own API key. -->
<script async defer src="https://maps.googleapis.com/maps/api/js?callback=initMap">
</script>

你必须使用lat，lng来指定位置。如果是国家或州名称，您应该获取位置的lat，lng并在代码中定义它。在隐藏的输入字段中插入php变量的值。在运行脚本时获取值并处理它。
