blocks|key|1352145|text|如果你的PHP服务器允许url+fopen包装器，那么最简单的方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1352146|$html+=+file_get_contents('https://stackoverflow.com/questions/ask');|code-block|syntax|javascript|1352147|如果你需要更多的控制，那么你应该看看cURL函数：|offset|length|1352148|$c+=+curl_init('https://stackoverflow.com/questions/ask');
curl_setopt($c,+CURLOPT_RETURNTRANSFER,+true);

If your PHP server allows url fopen wrappers then the simplest way is:

<pre><code>$html = file_get_contents('https://stackoverflow.com/questions/ask');
</code></pre>

If you need more control then you should look at the <a href="http://www.php.net/curl" rel="noreferrer">cURL</a> functions:

<pre><code>$c = curl_init('https://stackoverflow.com/questions/ask');
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
//curl_setopt(... other options you want...)

$html = curl_exec($c);

if (curl_error($c))
 die(curl_error($c));

// Get the status code
$status = curl_getinfo($c, CURLINFO_HTTP_CODE);

curl_close($c);
</code></pre>

you could use file_get_contents if you are wanting to store the source as a variable however curl is a better practive. 

<pre><code>$url = file_get_contents('http://example.com');

this solution will display the webpage on your site. However curl is a better option.

<a href="https://stackoverflow.com/questions/ask">https://stackoverflow.com/questions/ask</a>

then I want the HTML code of the page which is served. I want to retrieve this HTML code and store it in a PHP variable.

How can I do this?
