php - String get from CDATA, returned 0 when was converted to "int" -

i text include in cdata looks in xml file:

<?xml version="1.0" encoding="utf-8"?> <kml xmlns="http://splashurl.com/nztqga8 <document>  <name>opencellid cells</name> <description>list of available cells</description> <placemark><name></name><description><![cdata[lat: <b>3.378199</b><br/>lon:      <b>-76.523528</b><br/>mcc: <b>732</b><br/>mnc: <b>123</b><br/>lac: <b>4003</b><br/>cellid: <b>26249364</b><br/>averagesignalstrength: <b>0</b><br/>samples: <b>10</b><br/>changeable: <b>1</b>]]></description><point><coordinates>-76.523528,3.378199,0</coordinates></point></placemark> </document> </kml> 

i cdata text usign next code in php :

$ch = curl_init(); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_url, $url);    // url contents  $data = curl_exec($ch); // execute curl request curl_close($ch);   $xml = simplexml_load_string($data,'simplexmlelement', libxml_nocdata | libxml_noblanks); // permite  foreach ($xml->document->placemark $mensaje) $resuktado[]= (string) $mensaje->description.' ';  

how need lat, lon , cellid values, using this:

$string_array = explode("<br/>",$resuktado[$i]);// separar por salto de linea el string $latitud= explode(" ",$string_array[0]);  

and lattitud[1] lat value.

whe show value in scream looks this: 3.378199

but whe convert int value using:

echo (int) lattitud[1]; returns 0.

how can convert string int valule represents

the problem in code $latitud[1] contains string <b>3.378199</b>, not number self. there various ways fix it. here one, using regular expression;

preg_match("/\<b\>([^\<]+)/", $latitud[1], $match); $lat=$match[1]; // outputs 3.378199 

---

by way, in php, not need convert between string , int.

$a="1"; echo $a+1; 

puts 2. if feel need convert it, try

intval(). 

http://php.net/intval

if want rid of decimal use 1 of theese:

floor(); ceil(); round();
