I am trying to display markers on a Google Map from a PHP array containing lat & long values.

The PHP array looks like this at the moment:

Array
(
[0] => Array
    (
        [0] => 55.8490116, -4.222272800000042
        [1] => 54.5979369, -7.274279400000069
    )

[1] => Array
    (
        [0] => 55.8490116, -4.222272800000042
    )

)

I then add this array to a JS array on the PHP like so:

<script type="text/javascript">
var markers = <?php echo $myarray; ?>;
</script>

And then in my JS for the map it looks like:

var infowindow = new google.maps.InfoWindow();
var marker, i;
var bounds = new google.maps.LatLngBounds();

console.log(markers);

for (i = 0; i < markers.length; i++) { 

    var pos = new google.maps.LatLng(markers[1][0]);

    marker = new google.maps.Marker({
        position: pos,
        map: map
    });

    google.maps.event.addListener(marker, 'click', (function(marker, i) {

        return function() {
            infowindow.setContent(markers[1][0]);
            infowindow.open(map, marker);
        }

    })(marker, i));

}

I am not sure where to go next. I know my my array does not mimic what is required by the Google Maps API, but not sure how I can change it to suit.

Thanks Robert

我认为您的方法的问题在于呼应数组。

我尝试修复它的方法是在 JS 中创建一个名为 的空数组markers，循环遍历 PHP 数组的所有值，然后将每个值附加到markers.

另请注意，您在 PHP 中有一个数组数组，因此您需要一个嵌套循环。

如果您需要任何代码示例，请告诉我，否则就足够了。

你可以这样做：

<?php
$marker[] = array(
                "lat"=> '17.454000',
                "lng"=> '78.434952');
$marker[] = array(
                "title"=> 'shilparamam',
                "lat"=> '17.452665',
                "lng"=> '78.435608',
                "description"=> 'Mumbai formerly Bombay, is the capital city of the Indian state of Maharashtra.');
$marker[] = array(
                "title"=> 'image hospitals',
                "lat"=> '17.452421',
                "lng"=> '78.435715',
                "description"=> 'Pune is the seventh largest metropolis in India, the second largest in the state of Maharashtra after Mumbai.');
?>

                latlngbounds.extend(marker.position);

                        infoWindow.open(map, marker);
                    });
                })(marker, data);
            }
            map.setCenter(latlngbounds.getCenter());
            map.fitBounds(latlngbounds);
