How to parse this XML using PHP? - php

Question

I would like to do parse XML for the url:
http://www.opencellid.org/cell/get?key=myapikey&mcc=250&mnc=99&cellid=29513&lac=0
I am the beginner of PHP and tried the code as below:
$url = "http://www.opencellid.org/cell/get?key=myapikey&mcc=250&mnc=99&cellid=29513&lac=0";
$xml = simplexml_load_file($url) or die("feed not loading");
print_r($xml);
var_dump($xml);
I would like to do echo for each attribute e.g. lat, lon, range.. for this XML url.
I found many resource in stackoverflow which the XML is quite standard. I cannot find an example which is used for this format of XML:
Anyone could give me an idea? Thanks.

$url = "http://www.opencellid.org/cell/get?key=myapikey&mcc=250&mnc=99&cellid=29513&lac=0";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
$status = curl_getinfo($ch,CURLINFO_HTTP_CODE);
curl_close($ch);
if($status==200){
$x = new SimpleXMLElement($data,LIBXML_NOCDATA);
echo 'lat: '.$x->cell['lat'];
echo 'lon: '.$x->cell['lon'];
echo 'range: '.$x->cell['range'];
}
Update:
This is an alternative to curl. If you have curl installed, use curl, it is faster.
$url = "http://www.opencellid.org/cell/get?key=myapikey&mcc=250&mnc=99&cellid=29513&lac=0";
$data = file_get_contents($url);
$x = new SimpleXMLElement($data,LIBXML_NOCDATA);
$lat = $x->cell['lat'];
$lng = $x->cell['lon'];
$range = $x->cell['range'];
echo 'lat: '.$lat.'<br>';
echo 'lng: '.$lng.'<br>';
echo 'range: '.$range.'<br>';

$url = "http://www.opencellid.org/cell/get?key=myapikey&mcc=250&mnc=99&cellid=29513&lac=0";
$xml = simplexml_load_file($url) or die("feed not loading");
$attr = array("lat", "lon"); //list attr you require
foreach($xml->cell as $cell){
$data = $cell->attributes();
foreach ($attr as $key) {
// echo "<br>key: $key, value: " . $data[$key];
//edit to insert
$columns[] = $key;
$values[] = $data[$key];
}
echo $query = "insert into table_name(".implode(',',$columns).") values (".implode(',',$values).")";
}
