php - 如何使用php从url读取xml文件

Question

我必须从 URL 读取 XML 文件

$map_url = "http://maps.google.com/maps/api/directions/xml?origin=".$merchant_address_url."&destination=".$customer_address_url."&sensor=false";

这给了我一个像这样的 URL:

http://maps.google.com/maps/api/directions/xml?origin=Quentin+Road+Brooklyn%2C+New+York%2C+11234+United+States&destination=550+Madison+Avenue+New+York%2C+New+York%2C+10001+United+States&sensor=false

我正在使用这个函数来读取然后获取数据:

 $response_xml_data = file_get_contents($map_url);
 if($response_xml_data){
     echo "read";
 }

 $data = simplexml_load_string($response_xml_data);
 echo "<pre>"; print_r($data); exit; 

但是没有运气，有什么帮助吗？

您可以使用“simplexml_load_file”函数从 XML 中获取数据。请引用此链接

http://php.net/manual/en/function.simplexml-load-file.php

$url = "http://maps.google.com/maps/api/directions/xml?origin=Quentin+Road+Brooklyn%2C+New+York%2C+11234+United+States&destination=550+Madison+Avenue+New+York%2C+New+York%2C+10001+United+States&sensor=false";
$xml = simplexml_load_file($url);
print_r($xml);
