如何打一个网址，并使用PHP下载其XML [英] How to hit a url and download its xml using php

问题描述

我尝试过从网址获取xml，甚至smottt的想法从 PHP如何打开一个网址并下载它的XML ，但没有为我工作。

I tried everything to get the xml from the url, even smottt idea from PHP How to hit a url and download its xml , but didnt work for me.

我的场景;

产生美元汇率的网址：

nrb.org.np/exportForexXML.php?YY=2015&MM=03&DD = 01& YY1 = 2015& MM1 = 03& DD1 = 01

这里： YY MM DD YY1 MM1 DD1 是报告的结束日期。我相信，它在亚洲加德满都的unix时间生成一个xml。每次和第二个单独的xml文件名。

Here: YY MM DD are the starting date and YY1 MM1 DD1 are the ending date of report. I believe , it generates an xml in unix time of Kathmandu, Asia. Everytime and second seperate xml file name.

搜索互联网但没有任何内容，

Searched internet but nothing,

请帮助。

感谢提前

编辑：我使用的代码是

$url = "nrb.org.np/exportForexXML.php?YY=2015&MM=03&DD=01&YY1=2015&MM1=03&DD1=01";
$xml = new SimpleXMLElement($url, null, true);

foreach($xml->CurrencyConversionResponse as $CurrencyConversionResponse) {
    echo $CurrencyConversionResponse->BaseCurrency . "<br />";
    echo $CurrencyConversionResponse->TargetCurrency . "<br />";
    echo $CurrencyConversionResponse->ConversionTime . "<br />";
    echo $CurrencyConversionResponse->ConversionRate . "<br />";

}

错误讯息是

推荐答案

$ c> http：// 到网址

Add the http:// to the URL

$url = "http://nrb.org.np/exportForexXML.php?YY=2015&MM=03&DD=01&YY1=2015&MM1=03&DD1=01";
$xml = new SimpleXMLElement($url, null, true);

foreach($xml->CurrencyConversionResponse as $CurrencyConversionResponse) {
    echo $CurrencyConversionResponse->BaseCurrency . "<br />";
    echo $CurrencyConversionResponse->TargetCurrency . "<br />";
    echo $CurrencyConversionResponse->ConversionTime . "<br />";
    echo $CurrencyConversionResponse->ConversionRate . "<br />";
}
