<a href="http://us2.php.net/manual/en/function.http-get.php" rel="noreferrer"><code>http_get</code></a> should do the trick. The advantages of <code>http_get</code> over <a href="http://us.php.net/manual/en/function.file-get-contents.php" rel="noreferrer"><code>file_get_contents</code></a> include the ability to view HTTP headers, access request details, and control the connection timeout.

Remember that if you are using a proxy you need to do a little trick in your php code:

&lt;?php
$aContext = array(
 'http' =&gt; array(

blocks|key|1537873|text|根据你的php设置是否允许fopen+on+url，你也可以简单地在字符串中使用get参数来fopen这个url(比如http://example.com?variable=value+)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1537874|编辑:重读这个问题我不确定你是否想要传递变量-如果你不是，你可以简单地发送包含http://example.com/filename.xml的fopen请求-请随意忽略variable=value部分|1537875|entityMap|0|LINK|mutability|MUTABLE|url|http://example.com/?variable=value|1|http://example.com/filename.xml^0|1N|X|0|0|13|V|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

Depending on whether your php setup allows fopen on URLs, you could also simply fopen the url with the get arguments in the string (such as <a href="http://example.com?variable=value" rel="noreferrer">http://example.com?variable=value</a> )

Edit: Re-reading the question I'm not certain whether you're looking to pass variables or not - if you're not you can simply send the fopen request containg <a href="http://example.com/filename.xml" rel="noreferrer">http://example.com/filename.xml</a> - feel free to ignore the variable=value part

Guzzle is a very well known library which makes it extremely easy to do all sorts of HTTP calls. See <a href="https://github.com/guzzle/guzzle" rel="noreferrer">https://github.com/guzzle/guzzle</a>. Install with <code>composer require guzzlehttp/guzzle</code> and run <code>composer install</code>. Now code below is enough for a http get call.

<pre><code>$client = new \GuzzleHttp\Client();
$response = $client-&gt;get('https://example.com/path/to/resource');

echo $response-&gt;getStatusCode();
echo $response-&gt;getBody();

blocks|key|1537994|text|另一方面，在PHP中使用服务器的REST+API非常流行。您可以假设所有URL都是REST+API的一部分，并使用许多设计良好的PHP包。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1537995|实际上，REST+API是从站点使用服务的一种方式。|1537996|因此，有许多PHP包被开发来简化REST+API调用。例如，下面是一个非常好的例子：|1537997|https://github.com/romanpitak/PHP-REST-Client|code-block|syntax|javascript|1537998|使用这些包可以帮助您轻松获取资源。|1537999|因此，获取xml文件(您提到的)非常简单：|1538000|$client+=+new+Client('http://example.com');

$response+=+$request->getResponse();
echo+$response->getParsedResponse();|1538001|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|U|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|V|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|P|5|H|7|Y|8|@]|9|@]|A|$I|J]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

On the other hand, using the REST API of servers is very popular in PHP. You can suppose all URLs are parts of a REST API and use many well-designed PHP packages.
Actually, REST API is a way to use services from a site.
So, there are many PHP packages developed to simplify REST API call. For example here is a very nice one:
<pre><code>https://github.com/romanpitak/PHP-REST-Client
</code></pre>
Using such packages helps you to fetch resources easily.
So, getting the xml file (that you mentioned about) is as easy as:
<pre><code>$client = new Client('http://example.com');
$request = $client-&gt;newRequest('/filename.xml');
$response = $request-&gt;getResponse();
echo $response-&gt;getParsedResponse();
</code></pre>

I'm planning to use PHP for a simple requirement. I need to download a XML content from a URL, for which I need to send HTTP GET request to that URL.

How do I do it in PHP?
