Get a query from url in php - php

Question

I don't know how to do this in php. I am trying to get geocode data from openstreetmap.org but I need to do this in php.
In Javascript (and I have this working), it's:
<script type="text/javascript"
src="http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671">
</script>
I have that url but I don't know how to execute it in php.
I have tried:
<?php
$url = "http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671";
$response = file_get_contents($url);
?>
But this doesn't work. I tried the same with curl. Any ideas or is this type of query not possible in php?

Answer 1

Use this;
$xml = simplexml_load_file("http://nominatim.openstreetmap.org/reverse?format=xml&lat=43.642018&lon=-79.374671");
print_r($xml);
which will return you with an array of the values, see below;
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
)
)
Then manipulate the data however you see fit.

Answer 2

It does return
<?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>
That just means that there is no address for that particular coordinate.. This however has
http://nominatim.openstreetmap.org/reverse?format=xml&lat=52.5487429714954&lon=100
