file_get_contents when url doesn't exist
<p>I'm using file_get_contents() to access a URL. </p>

<pre><code>file_get_contents('http://somenotrealurl.com/notrealpage');
</code></pre>

<p>If the URL is not real, it return this error message. How can I get it to error gracefully so that I know that the page doesn't exist and act accordingly without displaying this error message?</p>

<pre><code>file_get_contents('http://somenotrealurl.com/notrealpage') 
[function.file-get-contents]: 
failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found 
in myphppage.php on line 3
</code></pre>

<p>for example in zend you can say: <code>if ($request-&gt;isSuccessful())</code></p>

<pre><code>$client = New Zend_Http_Client();
$client-&gt;setUri('http://someurl.com/somepage');

$request = $client-&gt;request();

if ($request-&gt;isSuccessful()) {
 //do stuff with the result
}
</code></pre>
