PHP从URL解析XML
作者:互联网
http://www.bank.lv/vk/xml.xml?date=20130530
$url = 'http://www.bank.lv/vk/xml.xml?date=20130530'; $xml = simplexml_load_file($url) or die("feed not loading"); $Rate = $xml->Currency[1]->Rate; echo $Rate; echo 'BREAK HTML'; echo "-----"; echo "// "; var_dump($xml); echo " //";
为什么HTML数据不输出?已经测试了很多教程,但没有获得如何从此XML输出数据
解决方法:
你必须把
$Rate = $xml->Currencies->Currency['1']->Rate;
代替
$Rate = $xml->Currency[1]->Rate;
因为$xml结构是
SimpleXMLElement Object
(
[Date] => 20130530
[Currencies] => SimpleXMLElement Object
(
[Currency] => Array
(
[0] => SimpleXMLElement Object
(
[ID] => AED
[Units] => 1
[Rate] => 0.14900000
)
[1] => SimpleXMLElement Object
(
[ID] => AUD
[Units] => 1
[Rate] => 0.52300000
)
[2] => SimpleXMLElement Object
(
[ID] => BGN
[Units] => 1
[Rate] => 0.35900000
)
[3] => SimpleXMLElement Object
(
[ID] => BYR
[Units] => 1000
[Rate] => 0.06290000
)
