Echo status message in php geonames timezone - php

Question

I'm using following code php to get timezone:
$url = 'http://api.geonames.org/timezone?lat=' . $latitude . '&lng=' . $longitude . '&username=demo';
$xml = simplexml_load_file($url);
foreach($xml->children() as $timezone)
{
echo "TimezoneId: ".$timezone->timezoneId." ";
echo "DstOffset : ".$timezone->dstOffset." ";
echo "GmtOffset : ".$timezone->gmtOffset." ";
}
it work but for latitude and longitude of Antartica for example it give error status message:
<status message="no timezone information found for lat/lng" value="15"/>
How to echo this message?
I'm tryng this:
if ($xml->status) {
echo "error: ".$timezone->status['message']. "";
}
but don't work

You are trying to get an element from object, which doesn't exist. In such a XML element you have attributes and some values like in your case: countryCode, countryName, dstOffset, gmtOffset and etc. If you use var_dump() the result you can see the error message is in these attributes, which is an array.
Here you are an example:
var_dump() on a location without problem:
object(SimpleXMLElement)#4 (12) {
["#attributes"]=>
array(1) {
["tzversion"]=>
string(11) "tzdata2014i"
}
["countryCode"]=>
string(2) "KG"
["countryName"]=>
string(10) "Kyrgyzstan"
["lat"]=>
string(7) "40.4246"
["lng"]=>
string(7) "74.0021"
["timezoneId"]=>
string(12) "Asia/Bishkek"
["dstOffset"]=>
string(3) "6.0"
["gmtOffset"]=>
string(3) "6.0"
["rawOffset"]=>
string(3) "6.0"
["time"]=>
string(16) "2015-07-09 19:53"
["sunrise"]=>
string(16) "2015-07-09 05:41"
["sunset"]=>
string(16) "2015-07-09 20:36"
}
And here a var_dump() of Antartica:
object(SimpleXMLElement)#4 (1) {
["#attributes"]=>
array(2) {
["message"]=>
string(41) "no timezone information found for lat/lng"
["value"]=>
string(2) "15"
}
}
You can easily handle and print this error message like that:
if ($xml->status) {
echo 'error:' . $timezone->attributes()->message;
}

try this,
<?php
$url = 'http://api.geonames.org/timezone?lat=' . $latitude . '&lng=' . $longitude . '&username=demo';
$xml = simplexml_load_file($url);
foreach ($xml->geoname as $o_location){
printf(
'Name %s<br>
lat is %s<br>
lon is %s<br>
geonameId is %s<br>
countryCode is %s<br>
countryName is %s<br>
fcl is %s<br>
fcode is %<br>
',
$o_location->name,
$o_location->lat,
$o_location->lng,
$o_location->geonameId,
$o_location->countryCode,
$o_location->countryName,
$o_location->fcl,
$o_location->fcode
);
}
?>
