我不知道如何在php中执行此操作。我正在尝试从openstreetmap.org获取地理编码数据,但我需要在php中执行此操作。
在Javascript中(我有这个工作),它是:
<script type="text/javascript"
src="http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671">
</script>
我有那个网址,但我不知道如何在php中执行它。
我试过了:
<?php
$url = "http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671";
$response = file_get_contents($url);
?>
但这不起作用。我用curl尝试了同样的方法。任何想法或这种类型的查询在php中都不可能吗?

使用此功能;
$xml = simplexml_load_file("http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671");
print_r($xml);
将返回一个值数组,见下文;
SimpleXMLElement Object
(
[@attributes] => Array
(
[timestamp] => Thu, 22 Mar 12 18:31:11 +0000
[attribution] => Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.
[querystring] => format=xml&lat=43.642018&lon=-79.374671
)
[result] => 1, Yonge Street, Corktown, Toronto, Ontario, M5B2H1, Canada
[addressparts] => SimpleXMLElement Object
(
[house_number] => 1
[road] => Yonge Street
[suburb] => Corktown
[city] => Toronto
[county] => Toronto
[state] => Ontario
[postcode] => M5B2H1
[country] => Canada
[country_code] => ca
)
)
然后操作您认为合适的数据。

确实返回
<?xml version="1.0" encoding="UTF-8" ?>
<reversegeocode timestamp='Thu, 22 Mar 12 18:07:13 +0000' attribution='Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.' querystring='format=xml&lat=100&Lon=100'>
<error>Unable to geocode</error></reversegeocode>
这只意味着该特定坐标没有地址..但是这有 http://nominatim.openstreetmap.org/reverse?format=xml&lat=52.5487429714954&lon=100
